Storing openssl file digest as shell variable?

I am executing the below command in bash

filehash=`openssl dgst -sha1 $filename`

When I echo $filehash

I get this

SHA1(myfile.csv)= bac9c755bac9709fa8966831d1731dff07e28e6c

How do I only get the hash value stored and not the rest of the string i.e.

bac9c755bac9709fa8966831d1731dff07e28e6c

Solution

  • Through sed,

    filehash=`openssl dgst -sha1 $filename | sed 's/^.*= //'`

    It removes all the characters upto the =(equal symbol followed by a space).
