Shell Script, Copy process using find.

Shell Programming and Scripting

Ok, so here is what I am looking for..
Shell script that uses find to look for one days worth of data using the modified date and then copies only those files to a specified directory.

I figured I could use grep and the find command to do this. It seems to work just fine from what I can tell... However....

When the file isn't created for that day and my shell script runs (cron job) this is the error I get. I was hoping to remove that error message as I dont need to know if there isnt any files. However, I created a simple echo just to test the functionality and I am still getting an error.

Here is the script.

#!/usr/bin/ksh
#The below specifies daily RX and RS files from the T00010 Folder
#It pulls only files that are one day old
#Created by: Techjunky
file1=`find /opt/gp00/data/T00010/CYC_REPORTS -mtime 0 | egrep -i 'RX010453'`
file2=`find /opt/gp00/data/T00010/CYC_REPORTS -mtime 0 | egrep -i 'RS010453'`
#The below script copies RX and RS files within the T00010 folder if they exist
#This process is used for EC2000 Reporting for customer 10453.  There is a windows scheduled task on WNP4694 to copy the files to a specified folder.
if [$file1]; then
  cp $file1 /opt/gp00/data/T00010/CYC_REPORTS/10453/RX/
else
  echo RX file does not exist!
  if [$file2]; then
    cp $file2 /opt/gp00/data/T00010/CYC_REPORTS/10453/RS/
  else
    echo RS file does not exist!
  fi
fi
exit 1

Here is the error message I get when there aren't files for that day.

./CYC_REPORTS_10453.sh[9]: []:  not found
RX file does not exist!
./CYC_REPORTS_10453.sh[13]: []:  not found
RS file does not exis

t!

basically my script runs, but there is no file there so I get the error message... It makes perfect sense why I am getting that error mesage I just cant think of the logic so this wont happen. Just getting the RX and RS echo messages would be enough.

Change

if [$file1]; then

to

if [ x$file1 != "x" ]; then

and

if [$file2]; then

to

if [ x$file2 != "x" ]; then

Space is required here.

First, try spacing things out. Do

if [ $file1 ]

and

if [ $file2 ]

and verify that the square brackets aren't being treated as content in the condition. If that doesn't help, try

if [ -n $file1 ]

and

if [ -n $file2 ]

and see if that works.

(I'm a bash guy, not a ksh guy, so I could be way off, here.)

Spacing the brackets out worked. Thanks bartus11!
