Situation:
I need a bash script that deletes all files in the current folder, except all the files mentioned in a file called ".rmignore". This file may contain addresses relative to the current folder, that might also contain asterisks(*). For example:
1.php
2/1.php
1/*.php
What I've tried:
GLOBIGNORE
but that didn't work well.I also tried to use find
with grep
, like follows:
find . | grep -Fxv $(echo $(cat .rmignore) | tr ' ' "\n")
It is considered bad practice to pipe the exit of find
to another command. You can use -exec
, -execdir
followed by the command and '{}'
as a placeholder for the file, and ';'
to indicate the end of your command. You can also use '+'
to pipe commands together IIRC.
In your case, you want to list all the contend of a directory, and remove files one by one.
#!/usr/bin/env bash
set -o nounset
set -o errexit
shopt -s nullglob # allows glob to expand to nothing if no match
shopt -s globstar # process recursively current directory
my:rm_all() {
local ignore_file=".rmignore"
local ignore_array=()
while read -r glob; # Generate files list
do
ignore_array+=(${glob});
done < "${ignore_file}"
echo "${ignore_array[@]}"
for file in **; # iterate over all the content of the current directory
do
if [ -f "${file}" ]; # file exist and is file
then
local do_rmfile=true;
# Remove only if matches regex
for ignore in "${ignore_array[@]}"; # Iterate over files to keep
do
[[ "${file}" == "${ignore}" ]] && do_rmfile=false; #rm ${file};
done
${do_rmfile} && echo "Removing ${file}"
fi
done
}
my:rm_all;
