remove _ as prefix from the multiple files in a directory in Soalris

Question

I have to remove _ which is as prefix for a file. I used:

for i in _*.txt; do mv ${i} ${i/#_/''}; done

but it does not change the names of the files which has space in between as _abc xyz-abc.txt

I want _ as prefix to be removed from all the files in a directory irrespective of space.

Answer 1

Try:

for i in ./_*.txt; do
  mv "$i" "${i#_}"
done

It assumed that you ran a POSIX shell - /usr/xpg4/bin/sh with Solaris 10 and earlier.
