Question

I need a .ksh script to place a time-stamp in the middle of a file name and add one of two diferent extensions.

Asked by: HIONSPD

I need a script to place a time-stamp in the middle of a file name but also is there a way to get the extension without hard coding it in the scripts?  For instance some files maybe a .CSV extension while some other may be a .TXT extension?

This is the script I have :

#!/bin/ksh
FILENAME="ZO_FIG_DLY_FILENAME.CSV"
base=$(basename $FILENAME .CSV)
timestamp=$(date "+%Y%m%d%H%M")
NEW_FILENAME="${base}_$timestamp.CSV"
echo $NEW_FILENAME

Any ideas..?
Thanks

FILENAME="ZO_FIG_DLY_FILENAME.CSV"
 echo ${FILENAME/*./}

Assuming filenames only contain a single '.' followed by the extension.  These should all work:

$ ./add-date.sh SOME_FILE.txt
$ ./add-date.sh OTHER_FILE.CSV
$ ./add-date.sh whatever-this-may-be.bigextension

#!/bin/ksh
FILENAME=$1
EXT=$(echo $FILENAME | sed 's/.*\.//')
base=$(basename $FILENAME .$EXT)
timestamp=$(date "+%Y%m%d%H%M")
NEW_FILENAME="${base}_$timestamp.$EXT"
echo $NEW_FILENAME

Why not use the ksh builtin functions and reduce it to one line as per ozo's solution?
