[SOLVED] List files inside a folder unless the absolute path

Issue

I want to write a script that lists all the files I have within a folder.

My try:

#!/bin/bash
if ! test -d "$1" ; then
  echo `pwd`/$1
else
  cd "$1"
for f in * ; do
  "$0" "$f"
done
fi

I invoke: sh /home/user/test.sh folder.

This script works only if I specify the absolute path of the script. I'm looking for a more general solution that works also if I specify the script relative path.

Solution

You can use the string-line solution inside the comments or write another script where you:

• pre-process the input
• add the full path
• then invoke the script

To do that, create another script test-rec.sh:

#!/bin/bash
if test "$0" = /* ; then
  echo "Absolute path"
  rec_cmd="`dirname "$0"`/test.sh"
elif test "$0" = */* ; then
  echo "Relative path"
  rec_cmd="`pwd`/`dirname "$0"`/test.sh"
else
  echo "Neither absolute or relative, I use the PATH"
  rec_cmd="test.sh"
fi
"$rec_cmd" "$1"

to be invoked in the same way, through sh test-rec.sh folder
