This might work in bash (i do not know bash all too well), but definitely not in ksh. I don't believe a POSIX-shell would fathom it.

You use 4(!) fork()s to manipulate a simple filename, which is a waste of resources. Much better: split the filename using variable expansion like you already did, but instead of splitting into name and extension (which you do not need) split into the first 4 characters and the remainder. Then simply add the additional underscore. I am sure you can work out how. (but please do not post it here until the threads o/p has responded)

I hope this helps.
