removing a range of characters in a filename
hi, I have quite a bunch of files with annoyingly long filenames. I wanted to cut the range of characters from 9-18 and just retain the first 8 characters and the .extension. any suggestion how to do it. thanks much.

Code:
original filename: 20000105_20000105_20100503.nc.asc
output filename: 20000105.asc

for x in `ls *.nc.asc`; do mv $x `echo $x|cut -d_ -f2`.asc; done

Code:
 
for i in *.nc.asc; do echo mv $i ${i%%_*}.${i##*.}; done

execute the above command and make sure it gives the correct mv command ouput.

If you are satisified then, remove the echo commmand and run it
