A simple way to check MD5sum

[anon222]

Here it is:


Name: Checksum
Description: Calculates  checksum.
Command: /usr/scripts/checksum %f
Pattern: *
Appearance: Check all the boxes except Directories

save the script as checksum
make executable
copy the file to /usr/scripts

Code:

#!/bin/bash
# Misko_2083

file="$@"

MD5=(`echo "" | awk '{print "TRUE","MD5", $0}'`)
SHA1=(`echo "" | awk '{print "FALSE","SHA-1", $0}'`)
SHA224=(`echo "" | awk '{print "FALSE","SHA-224", $0}'`)
SHA256=(`echo "" | awk '{print "FALSE","SHA-256", $0}'`)
SHA384=(`echo "" | awk '{print "FALSE","SHA-384", $0}'`)
SHA512=(`echo "" | awk '{print "FALSE","SHA-512", $0}'`)
