Sorry miss send, was not done yet. Have a .sh script that accepts an -s sparse file size. Only 2 suffix's are valid m and g. Been trying to get this line of code to strip out just the single letter. But it strips the letter and every thing to the right of it. Timagesize=`echo-n "${imagesize}" | sed 's/g.*$//'` I plan to strip just the m or g if its there and the result should be numeric. If not numeric know invalid suffix. Need help with the sed syntax. Or if there is better way I want to learn it. Thanks
