I'm using this command to remove files generated within the last , however the output has the following errors
Error messages :
-bash-4.2$ ./zip_files.sh
find: â*â: No such file or directory
gzip: /main/dir/sub-dir is a directory -- ignored
Files in this directory will be of these sequence,

i only want to remove the files removed and gzipped and compress the Error messages
Appreciate your response in replying back.
CodePudding user response:
Your script could look like the following. Note the quotes, note the usage of unquoted *
without a space, note the find
arguments, see man find
. Check your script with shellcheck!
#!/usr/bin/env bash
# prefer upper case variables only for exported variables
directory=/main/dir/sub-dir
if [[ -d "$directory" ]]; then
find "$directory"/* -maxdepth 1 -type f \
'(' -mtime 1 -delete ')' -o \
'(' -mmin -360 -exec gzip {} ';' ')'
fi
With bash arrays you can put comments between long argument lines:
cmd=(
find "$directory"/* -maxdepth 1 -type f
# delete somthing
'(' -mtime 1 -delete ')' -o
# gzip them
'(' -mmin -360 -exec gzip {} ';' ')'
)
"${cmd[@]}"
