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.
Code:
#!/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.
Code:
./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.

diff
DIFF(1) General Commands Manual DIFF(1)NAME
diff - differential file comparator
SYNOPSIS
diff [ -efbh ] file1 file2
DESCRIPTION
Diff tells what lines must be changed in two files to bring them into agreement. If file1 (file2) is `-', the standard input is used. If
file1 (file2) is a directory, then a file in that directory whose file-name is the same as the file-name of file2 (file1) is used. The
normal output contains lines of these forms:
n1 a n3,n4
n1,n2 d n3
n1,n2 c n3,n4
These lines resemble ed commands to convert file1 into file2. The numbers after the letters pertain to file2. In fact, by exchanging `a'
for `d' and reading backward one may ascertain equally how to convert file2 into file1. As in ed, identical pairs where n1 = n2 or n3 = n4
are abbreviated as a single number.
Following each of these lines come all the lines that are affected in the first file flagged by `<', then all the lines that are affected
in the second file flagged by `>'.
The -b option causes trailing blanks (spaces and tabs) to be ignored and other strings of blanks to compare equal.
The -e option produces a script of a, c and d commands for the editor ed, which will recreate file2 from file1. The -f option produces a
similar script, not useful with ed, in the opposite order. In connection with -e, the following shell program may help maintain multiple
versions of a file. Only an ancestral file ($1) and a chain of version-to-version ed scripts ($2,$3,...) made by diff need be on hand. A
`latest version' appears on the standard output.
(shift; cat $*; echo '1,$p') | ed - $1
Except in rare circumstances, diff finds a smallest sufficient set of file differences.
Option -h does a fast, half-hearted job. It works only when changed stretches are short and well separated, but does work on files of
unlimited length. Options -e and -f are unavailable with -h.
FILES
/tmp/d?????
/usr/lib/diffh for -h
SEE ALSO cmp(1), comm(1), ed(1)DIAGNOSTICS
Exit status is 0 for no differences, 1 for some, 2 for trouble.
BUGS
Editing scripts produced under the -e or -f option are naive about creating lines consisting of a single `.'.
