Use mv cmd

Code:

mv MVSTP_FID_FID_POS_20130205033112.txt MVSTQ_FID_FID_POS_20130205033112.txt

If the first part of the file names is always the same you can easily change them by means of rename. Beware that rename comes in two different flavours, mostly depending on your Linux distribution:

Code:

rename MVSTP MVSTQ MVSTP*

or

Code:

rename 's/MVSTP/MVSTQ/' MVSTP*

To avoid confusion or for portability, use the mv command - as suggested by Chris - and compute the new name using shell parameter substitution, e.g.

Code:

for file in MVSTP*
do
  mv $file ${file/MVSTP/MVSTQ}
done

Please see http://www.gnu.org/software/bash/man...eter-Expansion for details. On the other hand, if the pattern is not the same please clarify and show us different file names in order to see the common features.
