Hi Experts.

I need a Linux BASH script to find all of the "*.tar.gz" files in all of the immediate sub-folders and then run "gpg" to encrypt them, (see command example below) and afterwards remove them if the encryption is succssfully completed. Ialso  need to this to be able to run unattended as a CRON job.

Cheers,
Keith.
gpg --no-secmem-warning --verbose --encrypt-files -r user@domain.com /home/account/backup/folder1/*.tar.gz

> "*.tar.gz" files in all of the immediate sub-folders
You mean in all subfolders of given folder, or in this very given folder only(excuse me my poor English understanding)?
first case
 find /home/account/backup/folder1/ -name '*.tar.gz' | while read f; do gpg -options "$f" && rm -fv "$f"; done
latter case
 find /home/account/backup/folder1/ -maxdepth 1 -name '*.tar.gz' | while read f; do gpg -options "$f" && rm -fv "$f"; done

Hi ravenpl,

The First Option is the one I'm after.

Could you clarify yoyr anser a little for me and include all of the gpg options that I showed in my original question thanks?

gpg --no-secmem-warning --verbose --encrypt-files -r user@domain.com /home/account/backup/folder1/*.tar.gz

Cheers

find /home/account/backup/folder1/ -type f -name '*.tar.gz' | while read f; do gpg --no-secmem-warning --verbose --encrypt-files -r user@domain.com "$f" && rm -fv "$f"; done

find /home/account/backup/folder1/ -type f -name '*.tar.gz' # finds all files matching '*.tar.gz' in given folder, that output is piped to
while read f; do CMD; done # which reads line by line(filenames one by one) and feeds to CMD
gpg --no-secmem-warning --verbose --encrypt-files -r user@domain.com "$f" && rm -fv "$f" # does the encryption and removes the file only if encrypting hasn't failed

Very neat... can you confirm that "find" will search all of the sub-folders below "/home/account/backup/" if I call it as "find /home/account/backup/"?

Yes, it will list all names in all subfolders.
Note: I added "-type f" to list regular files only
