There is no need for ls. In fact, in many cases, it will cause problems when there are spaces in the filenames.
Code:
n=1
for f in somestring_*
do
  num=$( printf "%03d" "$n" )
  n=$(( $n + 1 ))
  nf=somestring_$num
  mv "$f" "$nf"

NAME
rename - rename files SYNOPSIS
rename [options] expression replacement file... DESCRIPTION
rename will rename the specified files by replacing the first occurrence of expression in their name by replacement. OPTIONS
-v, --verbose Give visual feedback which files where renamed, if any. -V, --version Display version information and exit. -s, --symlink Peform rename on symlink target -h, --help Display help text and exit. EXAMPLES
Given the files foo1, ..., foo9, foo10, ..., foo278, the commands rename foo foo0 foo? rename foo foo0 foo?? will turn them into foo001, ..., foo009, foo010, ..., foo278. And rename .htm .html *.htm will fix the extension of your html files. WARNING
The renaming has no safeguards. If the user has permission to rewrite file names, the command will perform the action without any ques- tions. For example, the result can be quite drastic when the command is run as root in the /lib directory. Always make a backup before running the command, unless you truly know what you are doing. SEE ALSO
mmv(1), mv(1) AVAILABILITY
The rename command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. util-linux June 2011 RENAME(1)
