hello all,
i have a string "start(hello) welcome to unix end(hello)start(hi) welcome 2 unix end(hi)". note that this is a string & not a file. i want to look for the word end & insert (xxxx) before it.
so my string at the end of the operation shud b
"start(hello) welcome to unix (xxxxx)end(hello)start(hi) welcome 2 unix(xxxxx) end(hi)".
if putting the string in a file & then manipulating is easier, i don't mind doing that. but i wud prefer direct string manipulation.
thanx in advance
sandeep

Hi:
A way ....
# all on one line
echo "start(hello) welcome to unix end(hello)start(hi) welcome 2 unix end(hi)" |awk ' { gsub("end","$xxxx$end"); print $0 } '
The above uses awk to substitute xxxxend for end. Note escaping the special characters ()
