Question

Im wondering how to make this script work:

for f in *.php
do
    for c in seq 1 $#
    do
            eval `eval echo \$$c`
    done
done

The main idea of the script y to execute all commands passed to the script on every file, for example:

bash script.sh "grep text \$f" "echo \"Done!\""

Should be the same as:

for f in *.php
do
     grep text $f
     echo "Done!"
done

I think it’s pretty simple but I’ve been stuck here for long
Any help?

Answer 1

You can make it work like this:

for f in *.php
do
  for arg
  do
    eval "$arg"
  done
done

A more common (and safer) approach would be

find *.php -print0 | xargs -0 -I{} "$@"

which could be run as ./yourscript grep text {}, but it doesn’t allow arbitrary shell constructs.
