help with shell script: cp command not working, but mv command works...
Hello.
I would like to ask your help regarding the cp command. We are using a cp command to create a back-up copy of our file but to no avail. It's just not working. We already checked the file and directory permissions and all seems correct.
We have a script (ftp.script) which calls on another script (copy.script).
copy.script is expected to create a copy of the file called "newfile.mmddyy" from /usr/tmp/data to /usr/tmp/work.
the result is we are getting a zero return code from the cp command but when we do a file listing command, it says that the file does not exist.
Code:
copy.script
#!/usr/bin/ksh
FILE_BKUP=Y
ADD_DATE_TIME_SUFFIX=N
filename=newfile.mmddyy
pathfile=/usr/tmp/data/$filename
WORKPATH=/usr/tmp/work
LOGPATH=/usr/tmp/logs
if [[ "$FILE_BKUP" = 'Y' ]]
then
if [[ "$ADD_DATETIME_SUFFIX" = 'Y' ]]
then
cp $pathfile $WORKPATH/$filename.$DATESTAMP
rc=$?
else
cp $pathfile $WORKPATH/$filename
rc=$?
echo `ls -latr $WORKPATH/$filename` >> $LOGPATH/script.log
fi
fi
result:
+ [[ Y = Y ]]
+ [[ N = Y ]]
+ cp /usr/tmp/data/newfile.mmddyy /usr/tmp/work/newfile.mmddyy
+ rc=0
+ ls -latr /usr/tmp/work/newfile.mmddyy
ls: 0653-341 The file /usr/tmp/work/newfile.mmddyy does not exist.
What we did was to have the ftp.script check on /usr/tmp/work directory if the file exists there. If it doesn't exist there, the script will create a copy of the file on another work directory, /usr/tmp/work2, using the cp command and then move the file from /usr/tmp/data to /usr/tmp/work.
Code:
ftp.script
if [[ -a $workdir/$1 ]];
then
rm -f $datadir/$1
else
cp $datadir/$1 $workdir2/$1.copied_by_script.ftp
mv $datadir/$1 $workdir/$1
fi
where datadir=/usr/tmp/data, workdir=/usr/tmp/work and workdir2=/usr/tmp/work2. /usr/tmp/work2 has a dir permission of 2775, owner is usrdcrd and group is usrdeliv.
Since the file does not exist on /usr/tmp/work directory, I'm expecting ftp.script to create a copy of the file on /usr/tmp/work2 and move the file from /usr/tmp/data to /usr/tmp/work. But it only moved the file from /usr/tmp/data to /usr/tmp/work, again, the cp command did not work.
By the way, the file came from a SAP server and sent to the AIX server. Once the file reaches AIX server, a script is executed. This script then calls on the ftp.script to start the processing of the file. The owner/permission/group of the file when it reached AIX is : permission of 660, owner is usradm1 and group is usrdeliv.
Hi,

pwd
PWD(1) BSD General Commands Manual PWD(1)NAME
pwd -- return working directory name
SYNOPSIS
pwd [-L | -P]
DESCRIPTION
The pwd utility writes the absolute pathname of the current working directory to the standard output.
Some shells may provide a builtin pwd command which is similar or identical to this utility. Consult the builtin(1) manual page.
The options are as follows:
-L Display the logical current working directory.
-P Display the physical current working directory (all symbolic links resolved).
If no options are specified, the -P option is assumed.
ENVIRONMENT
Environment variables used by pwd:
PWD Logical current working directory.
EXIT STATUS
The pwd utility exits 0 on success, and >0 if an error occurs.
SEE ALSO builtin(1), cd(1), csh(1), sh(1), getcwd(3)STANDARDS
The pwd utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
BUGS
In csh(1) the command dirs is always faster because it is built into that shell. However, it can give a different answer in the rare case
that the current directory or a containing directory was moved after the shell descended into it.
The -L option does not work unless the PWD environment variable is exported by the shell.
