Iterating a file using a basic for loop in bash

Another one I always use - doing some command over every line of a file:

for i in `cat foo.txt`; do echo $i; done

Nice and simple, but works a treat.

anon:

This doesn't work using unxutils (for win32: see http://unxutils.sf.net ) if the file names have spaces in.

jesse:

Yeah, that won't do what you expect if there are lines with whitespace in them.

If you strictly want to process things a line at a time, you can do something like--

cat foo.txt | while read i; do echo $i; done
