How do I cut a string within a string
Hi Here is my requirement:

I am reading a string, once its done, need to send into different args.

For eg:
echo "Enter reason for "
read myreason
?????
?????
echo STR1, STR2, STR3, STR4

Output:
myreason: build_XXX.XX.XX_stop_intranet
STR1=build
STR2=XXX.XX.XX
STR3=stop
STR4=intranet

thanks in advance.
No.of characters may vary depends on reason.
some cases myreason:abcdefgh_XX.XXX.XXX_restart_application

Code:
myreason=build_XXX.XX.XX_stop_intranet
IFS=_
set -f
set -- $myreason
STR1=$1
STR2=$2
STR3=$3
STR4=$4

Sorry.. its working, but having issues within my script.
I am reading myreason within my script which takes arguments
For eg: runscriptA arg1 arg2 arg3

I am reading the myreason within script "runscriptA". After I read, it replaces my arguments arg1 with the recent $1, arg2 with $2... any other solution?
