Ok, I'm trying to use the right tools. What's the right CL tool for replacing a string within a string? perl is an obvious choice. So, how would I replace a given string in another string using do shell script?


You could have a look at the 'sed' utility.
For example, replacing 'def' by 'xyzt' in 'abcdef':
% echo 'abcdefg' | sed 's/def/xyzt/'
abcxyztg
Another utility, 'tr', may also prove useful.
Of course, the usual cautions about special characters apply.

HTH,
Axel
