How to apply shell command to each line of a command output?
bash
Solution
It's probably easiest to use `xargs`. In your case:
ls -1 | xargs -L1 echo
The `-L` flag ensures the input is read properly. From the man page of `xargs`:
-L number
Call utility for every number non-empty lines read.
A line ending with a space continues to the next non-empty line. [...]
Problem
Suppose I have some output from a command (such as `ls -1`): ``` a b c d e ... ``` I want to apply a command (say `echo`) to each one, in turn. E.g. ``` echo a echo b echo c echo d echo e ... ``` What's the easiest way to do that in bash?
