sed 's |$  ;s | : g' infile

if you have Python

python -c "print '\n'.join([line.strip()[:-1].replace('|',':') for line in open('file')])"

it is showing :s not found

Could you post (copy/paste) the exact command and (error) messages from your terminal?

its working thatnks a alot addict............

Or if you have perl:

perl -ne '{s/\|$//; s/\|/~/g; print}' <file_name>
