Some pointers: You can use sed s command to first replace the string '@.*' with the null string and then replace the string '.*:' with the null string, which leaves the word before the '@' but after the preceding ':'.
Another tip: using ; command separator character you can specify both s commands in one sed command line.

See sed man page for more info.

Hi

Pointer b) : Capture the string preceding the monkey tail ( @ ) composed by any number of non-colon ( : ) characters and replace the whole string with the captured part.

Tip b) : search this forum.
