    I have few files namely - "a", "b", "c",etc.. I want to add the keyword: ".mov" to all files in that folder.

    Please suggest me an approach which script will be best suited for this - AppleScript, Shell, Python etc. (I being a non-scripting guy).

    Note: I m using MacOSX-Maverics[Terminal].

    Something like this ought to work:

    #!/bin/sh
for i in *; do
  mv "$i" "$i.mov"
done

    Put that in the directory above the directory with your files. Use chmod +x script.sh, then from within the directory with your files, ../script.sh.

    EDIT: This assumes your 'set' of files is every file in that directory. If it isn't, you'll need to more clearly define your set.

    I would like to batch rename files (*.txt) by inserting a number of the format 'RXR1234567' (RXR+7digits) [if such number (and ideally only one) is found in the text] at the front of the filename, e.g. instead of 

    letter_235.txt

    the file should be called 

    RXR1234567_letter_235.txt

    Could this be done from the command line (grep, rename)? The files are in various subdirectories.

    Your thoughts will be appreciated (as always).

    Try this in the root directory:

    find -name '*.txt' -exec sh -c 'PREFIX=`grep -m 1 -oe "RXR[0-9]\{7\}" "$0"` && mv "$0" "${0%/*}/${PREFIX}_${0##*/}"' {} \;

    Note: If a file contains multiple matches of the pattern the first one will be used.
