在不同目录的当前目录中运行脚本

Question

I run a script which compresses certain files and rename them. I don't want to copy it to each directory and operate it from inside

how can I run it from outside the target directory to act on it, tried

'bash compress.sh target_dir/'

In a bash script you can use input via $1 for the first input ($2 for second,..). You could write your script such that it is working with this. Easiest way might be to store pwd

#!/usr/bin/env bash
baseDir=$PWD
cd "$1" || echo 'Check input'; exit 1
# ..your stuff..
cd "$baseDir" || :

To do this for all sub directories you can use find and a loop:

#!/usr/bin/env bash
baseDir=$PWD # or any other path
allSubDirectories=$(find "$baseDir" -type d)
for d in $allSubDirectories
do
  cd "$d" || :
  # ..your stuff..
  cd "$baseDir" || :
done
