Help with find in a script
Hi,

I am trying to find files in a directory. I am passing a part of the file name as parameter 3 in my script. but my find command doesn't see
to take it correctly

Code:
find $IRC_PATH -type f -name `${3}`*.gz -print

Here $3 is part of file name I am passing as parameter. My files will look like this

Code:
MINUTES.REF_STG.20100303.txt.tar.gz


I am passing $3 as MINUTES.REF_STG. But my find command above doesn't see to get the file names correctly. I mean its not printing
any files even though they exist in that directory. I am in the correct directory as well.

how should i change the above find command for it to pick files with the names like MINUTES.REF_STG.20100303.txt.tar.gz

Replace the backticks (`) with double quotes ("), and extend them to include the "*.gz" part, and you should be good to go.

In Bash, specify positional parameters with $1 .. $9 or ${1} .. ${n} with n being more than 2 digits. You have `${3}` which tells Bash to execute parameter 3 and return that interpreted value.

Also "set -x" is your friend!

Code:
#!/bin/bash

set -x

one=$1

one=${1:-First_Default}

two=${2:-Second_Default}

thr=${3:-Third_Default}

nam="$thr*.gz"

echo "find $one -type f -name $nam -print"

#also
echo "find $one -type f -name $3*.gz -print"

#and
echo "find $one -type f -name ${3}*.gz -print"

I am extending the script to delete files older than 20 days. I am passing that as parameter too.

Quote:
find $IRC_PATH -type f -name "${3}*.gz" -mtime +"{4}" -exec rm -rf {} \;
how come this is throwing out error
Quote:
find: invalid argument `+{4}' to `-mtime'
I am running korn shell

---------- Post updated at 01:53 PM ---------- Previous update was at 01:48 PM ----------

i think i got it. Missed $.

But my find is recursively going through all sub-directories. Is there a way to limit it to only the present directory.

You should have:

Code:
$IRC_PATH -type f -name "${3}*.gz" -mtime +"${4}" -exec rm -rf {} \;

no?
