UNIX script to find existences of files with a pattern in name
Hi
My requirement is as follows.

In a particular source directory say /home/Source, I need to search for filename with the following pattern.

Bank_YYYYMMDD.txt

and if the files with patterns are found them move them to archive directory /home/Source/Archive.

The script should not do anything if no file is found.

Thanks.

Hi, what have you tried so far?

Here is what I have done.
Code:
#Script starts
#!/bin/ksh
SOURCE_DIR=/home/infa_usr/bjoe
ARCHINVE_DIR=${SOURCE_DIR}/Archive
for FILENAME in `ls $SOURCE_DIR/Bank\_????????.txt`
do
        echo "Archving File $FILENAME"
        mv $FILENAME $ARCHINVE_DIR
done
#Script ends

Code:
/home/infa_usr/bjoe->ls -l Bank*
-rw-r--r--    1 infa_usr informat          0 Mar  4 12:44 Bank_20110102.txt
-rw-r--r--    1 infa_usr informat          0 Mar  4 12:44 Bank_20140101.txt
/home/infa_usr/bjoe->./test.ksh
Archving File /home/infa_usr/bjoe/Bank_20110102.txt
Archving File /home/infa_usr/bjoe/Bank_20140101.txt
/home/infa_usr/bjoe->./test.ksh
/home/infa_usr/bjoe/Bank_????????.txt not found

If the files are found then scripts runs fine, but if there are no files matching pattern, then I get the "not found" message. Is there a way to handle this so that this message is not displayed on the terminal.

Thanks.

Try:
Code:
cd "$SOURCE_DIR"
for FILENAME in Bank_????????.txt
do
  if [ -f "$FILENAME" ]; then
    # mv operations
  fi
done

Scrutinizer,
The code you provided bellow does work perfectly. Thanks for the code.

Can we extend it further that we pass the pattern "Bank\_????????.txt" (or any generic pattern) from command line. I tried to change
Bank_????????.txt
to
$1
or
"$1"
and then passed the argument as Bank_????????.txt to the script, but that does not work.

Thanks.

Yes you could try:
Code:
pattern=$1
cd "$SOURCE_DIR"
for FILENAME in $pattern
do
  if [ -f "$FILENAME" ]; then
    # mv operations
  fi
done

And call with:
Code:
./script.sh "Bank_????????.txt"

The quotes around the pattern are important.


--or--
Code:
cd "$SOURCE_DIR"
for FILENAME
do
  if [ -f "$FILENAME" ]; then
    # mv operations
  fi
done

And call with:
Code:
./script.sh Bank_????????.txt

Code:
#Script starts
#!/bin/ksh
SOURCE_DIR=/home/infa_usr/bjoe
ARCHINVE_DIR=${SOURCE_DIR}/Archive
.
.
.

Note that the shebang should be the very first line in your script.
