If statement for substring within string (korn)

Hi all,

Just looking for a simple if statement that searches for a substring within a varaible, and then performs some function.

Problem is that I need it to work in Korn shell

$var = *string* does not work in Korn


want to find 00.00

Are you sure you have it right? It works in most korn shells, even many ksh88. Try:

[[ "$var" == *234* ]] && echo "var matches

it should print "var matches".

If it doesn't, what is your system, what is your shell?

For shells that don't, you can sometimes do:

if ! [ "${STR}" = "${STR/substring/}" ]
       echo "substring is inside ${STR}"

It seems as though that now works, perhaps a syntax error on my part at some point. I would like to use that argument to make some changes to filenames, however it appears as though I have some other errors as well.

Thank you for the help
