how to delete blanks inside a quoted string
Hi
I need to update a string inside a file which looks like the following:
PX_LIST=" 4119 2390 2294 2776 2897 4099 "
Is there a way to get rid of the blanks after the first quote mark and before the last quote mark.
This needs to be done ONLY for the string named PX_LIST (there are some other qutes in the file and the blanks needs to be preserved for them)
The modifies string should look like this:
PX_LIST="4119 2390 2294 2776 2897 4099"
Any idea? Thanks for any help and/or advice.... -A
