The real kicker is the time difference, the top being the 'function method' and the bottom being the 'redirect-source' method. To prove this theory, the timing speaks for itself:. This is the bottom part of about results, done at random intervals. Hopefully this will help future visitors to this question didn't want to keep it to myself.
How do I solve this problem? You need to use shell function instead of an alias to get rid of this problem. You can define foo as follows:. There are legitimate technical reasons to want a generalized solution to the problem of bash alias not having a mechanism to take a reposition arbitrary arguments. One reason is if the command you wish to execute would be adversely affected by the changes to the environment that result from executing a function. In all other cases, functions should be used.
What recently compelled me to attempt a solution to this is that I wanted to create some abbreviated commands for printing the definitions of variables and functions. So I wrote some functions for that purpose. However, there are certain variables which are or may be changed by a function call itself.
The basic command I had been using in a function to print variable defns. This won't print the definitions of the variables mentioned above as they are in the current context , e. But my function tells me the wrong information:. One solution I came up with has been mentioned by others in other posts on this topic.
For this specific command to print variable defns. However, I still felt compelled to find a solution that works for arbitrary numbers of arguments. A nice thing about this solution is that all the special tricks used to handle positional parameters arguments to commands will work when composing the trapped command.
The only difference is that array syntax must be used. If you're looking for a generic way to apply all params to a function, not just one or two or some other hardcoded amount, you can do that this way:. For example, if i did runjar hi there it would end up actually running java -jar myjar.
If i did runjar one two three it would run java -jar myjar. Functions are indeed almost always the answer as already amply contributed and confirmed by this quote from the man page: For completeness and because this can be useful marginally more lightweight syntax it could be noted that when the parameter s follow the alias, they can still be used although this wouldn't address the OP's requirement.
This is probably easiest to demonstrate with an example:. This can be useful for commands which take complex arguments my memory isn't what it use t be anymore Thank you for your interest in this question.

Would you like to answer one of these unanswered questions instead? Make a Bash alias that takes a parameter? Trash" In Bash, this does not seem to work. Hello 4, 3 11 6. How to pass command line arguments to a UNIX alias?
This question is off-topic for SO. It was answered on UNIX. SE , and the answer is that you don't even need to bother: You doesn't even have to declare the alias. Just defining the function will do. If you are changing an alias to a function, source ing your. Since aliases are higher precedent than functions, it will try to use the alias. Perhaps I'll save someone the 5 minutes I just wasted. One time-saving trick I learned at Sun is to just do an exec bash: It will start a new shell, giving you a clean read of your configs, just as if you closed and reopened, but keeping that session's environment variable settings too.
Also, executing bash without the exec can be useful when you want to handle thinks like a stack. Similarly, for the actual question: Mike Gleason 1, 1 9 5. I prefer this answer, as it shows iterating through the array of arguments that might come in. And the spaces after the first bracket and before the last bracket are required as well. I think you want something like this: Evan Langlois 1, 11 This answer says it all.
If I'd read from the bottom of this page, I'd have saved some time. It was supposed to be a general explanation that you don't have alias parameters, you use a function instead. The given function was just an example to counter the original example. If you would like to contribute your thoughts to this attempt at a nomenclature, please email the webmaster: The child of a business employee or executive who is living in, or has lived overseas in a foreign culture.
Though all children of businessmen and businesswomen could be called by this name, this term especially refers for those who have lived overseas. Expatriate - noun or verb As a noun, an expatriate is sometimes referred to with the abbreviated term, "expat. As a verb, this word means to leave one's home culture to live in another. Note that this term has absolutely nothing to do with patriotism, which is an entirely different concept. The ex patriat e may or may not be patriot ic --the words are in no way synonymous!
Some expatriates feel extremely patriotic upon returning to their homeland, while others may feel disenfranchised and disappointed.
When that person returns to the home culture, he or she is called a "repatriate" or "repat. Expatriate Lifecycle - the entire process of expatriation and repatriation. Ideally, this involves the assessment and selection of the overseas candidate, pre-departure training, the overseas experience, preparing for reentry, reentry hopefully leading to adjustment , and perhaps preparation for subsequent overseas assignments.
Global Nomad - one who grows up in a country or countries other than their passport country. This term implies an internationally transient childhood. Home Culture - the culture with which one feels the strongest affinity. This may be the culture of one's birth, passport, or a culture in which one has lived, as all three of these places may be different for a TCK.
Host Culture - the foreign culture in which one lives while they are not in their own home culture. This may lead to a separationist and sometimes elitist attitude among some MBs. Natural rivalries -- some playful, others more painful -- include the specific branch of service such as: Army Brat, Navy Brat, etc.
This is an area in which much more research is warranted! As a result, they frequently identify even more strongly with that foreign culture than the culture of their parents.
Yet, they still can't "fit in" because they are not originally of that host culture. MKs are more likely to be bi -cultural, as opposed to multicultural. You can see a lot by looking Visualizing, clustering, performing dimensionality reduction: Often such methods inspire predictive analysis methods used later. Should one combine a weighted sum of 10 rules or 10,? One way of framing such questions of model selection is to remember why we build models in the first place: While the latter is difficult to quantify, the former can be framed not only quantitatively but empirically.
Comparing the value of this loss function for models of differing complexity yields the model complexity which minimizes generalization error. Above we mentioned that models are built to predict and to interpret. Which brings us to… iNterpret: The predictive power of a model lies in its ability to generalize in the quantitative sense: The interpretability of a model lies in its ability to generalize in the qualitative sense: The world rarely hands us numbers; more often the world hands us clickstreams, text, graphs, or images.
Interpretable modeling in data science begins with choosing a natural set of input features — e. In this step, domain expertise and intuition can be more important than technical or coding expertise. Next one chooses a hypothesis space, e. Each of these might have advantages in terms of computational complexity vs interpretability. For example, interpretability can be aided by learning by boosting or with an L1 penalty to yield sparse models; in this case, models which can be described in terms of a comprehensible number of nonzero weights of, ideally, individually-interpretable features.
Rest assured that interpretability in data science is not merely a desideratum for the natural scientist. Startups building products without the perspective of multi-year research cycles are often both exploring the data and constructing systems on the data at the same time.
Interpretable models offer the benefits of producing useful products while at the same time suggesting which directions are best to explore next.
For example, at bit. In most cases, topic identification was straightforward, e. One particular click pattern was difficult to interpret, however; with further exploration we realized that people were using bit. It requires creative decisions and open-mindedness in a scientific context.
Our next post addresses how one goes about learning these skills, that is: Thanks to Mike Dewar for comments on an earlier draft of this. One thing that bugs me though — the compressed link urls. These data are often measuring phenomena in […]. I know you work there and all, but a blog post full of bit. Google gives me this link: Nice article, but I agree with the commenters before me: I shudder when I see someone try to analyse with tools, you should analyse with concepts and the tools simple give you the values.
Whether you use Perl, scripts, C or Excel makes no difference, its the values you are after. I was expecting things more along the line of hierarchical, relational, aggregation, etc. A Taxonomy of Data Science. For those who were bugged by the bit.
Understanding databases and querying data is hugely important. I saw the title of the post from another blog and was hoping to see relationships between the different types of data processing as calibration, reduction, visualizing, etc. I think tools do matter, though your point about using concepts is valid.
