Question

I am working on linux scripts and want to extract a substring out of a master string as in the following example :-

Master string =

2011-12-03 11:04:22#Alex#Audrino^13b11254^Townville#USA#    

What I require is :-

Substring =

13b11254    

I simply want to read and extract whatever is there in between ^ ^ special characters.

This code will be used in a linux script.

Answer 1

POSIX sh compatible:

temp="${string#*^}"
printf "%s\n" "${temp%^*}"

Assumes that ^ is only used 2x per string as the 2 delimiters.
