How to write a script for text file encryption?

[shanbalao]

Hi All,

I have zero knowledge in UNIX, so i desperately need the help from you guys.

I need a script which can encrypt all the text files in one shot in a source directory.
After all the text files are encrypted, they will be put into a separate folder.

Command involve:
gpg with -a, --armor

eg.
Before encyption:
/main/project/sorce/file1.txt
/main/project/sorce/file2.txt
/main/project/sorce/file3.txt

Before encyption:
/main/project/target/file1.txt.gpg
/main/project/target/file2.txt.gpg
/main/project/target/file3.txt.gpg

I don't think you can do it in "one shot", but a simple bash loop should do it for you.

Read up on loops in bash, and read the gpg manpage and you should have your script within minutes.

I can't post a link but here's the syntax you need for gpg:

echo password | gpg --batch -q --passphrase-fd 0 --cipher-algo AES256 -c /tmp/file.tgz

Create a basic bash script that uses the first parameter as the path to the plaintext file and create a loop as suggested above. You can then do things like: ./batchencrypt *.doc
