bash "map" equivalent: run command on each file
- by Claudiu
I often have a command that processes one file, and I want to run it on every file in a directory. Is there any built-in way to do this?
For example, say I have a program data which outputs an important number about a file:
./data foo
137
./data bar
42
I want to run it on every file in the directory in some manner like this:
map data `ls *`
ls * | map data
to yield output like this:
foo: 137
bar: 42
