I am not sure if it can be done in a single unix command, but this small script may help you

#!/usr/bin/ksh

for k in PMC*.arc
do
   newfilename=`echo $k | sed 's/1//g'`
   cp $k $newfilename && rm $k
done

Hi,

In your previous post it was not mentioned.

try this,

ls PMC1*.arc | while read k; do cp $k `echo $k |sed 's/\(.*\)1_\(.*\).arc/\1_1_\2\.arc/g'` && rm $k; done
