I would like to remove duplicate entries from a file. The file looks like this:
xyabcd1:5!b4RlH/IgYzI:cvsabc
xyabcd2:JXfFZCZrL.6HY:cvsabc
xyabcd3:mE7YHNejLCviM:cvsabc
xyabcd1:5!b4RlH/IgYzI:cvsabc
xyabcd4:kQiRgQTU20Y0I:cvsabc
xyabcd2:JXfFZCZrL.6HY:cvsabc
xyabcd1:5!b4RlH/IgYzI:cvsabc
xyabcd2:JXfFZCZrL.6HY:cvsabc
xyabcd4:kQiRgQTU20Y0I:cvsabc
xyabcd2:JXfFZCZrL.6HY:cvsabc
How can I remove the duplicates from this file by using shell script?
From the sort manpage:
