What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

IFS - use entire lines in your for cycles

IFS - use entire lines in your for cycles

When you use a "for" construct, it cycles on every word. If you want to cycle on a line-by-line basis (and, well, you can't use xargs -n1 :D), you can set the IFS variable to .


There are 4 alternatives - vote for the best!

Terminal - Alternatives

Know a better way?

If you can do better, submit your command here.

What others think

Not bad. Here's an alternative using read (this doesn't require you to change IFS)

while read i; do echo "$i"; done < file

(You can cat the file into the while, if you prefer)

If you *do* want to alter IFS, you can do it more simply (in bash at least) like this:

export IFS=$'\n'

A good idea is also to start with a OLDIFS=$IFS

Then your loop

Then back to real life with IFS=$OLDIFS

You can avoid problems by doing this

IFS is a shell-local variable, so there's no need to export it.
