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,

sadc
sadc(8) BSD System Manager's Manual sadc(8)NAME
sadc -- system activity data collector
SYNOPSIS
/usr/lib/sa/sadc [-m mode] [t n] [ofile]
DESCRIPTION
The sadc tool is used to collect cumulative system activity data. The sample system data is collected at intervals t seconds apart, in a
loop n times. The binary sample data is written to ofile if specified. Otherwise, the binary data is written to stdout. If the ofile file
does not exist, it is created, otherwise it is truncated.
sadc is intended to be used as the engine behind the sar(1) command, and is not typically invoked on the command line. Two shell scripts,
sa1 and sa2, are provided to drive the typical sampling, saving, and reporting process.
OPTIONS
The following options modify the way data is collected by sadc.
-m mode Modify the collection of system statistics as specified by mode. Currently only one mode is supported.
PPP By default, the collection of ppp network interface statistics is turned off. This is because the number of ppp connec-
tions can be very high, causing the raw data file to grow unexpectedly large, especially when samples are collected at
short intervals. Use the PPP mode to turn the collection back on.
EXAMPLES
/usr/lib/sa/sadc 15 20 /tmp/sample.out
This call collects 20 samples at 15 second intervals. The binary data is written to the /tmp/sample.out file
FILES
/var/log/sa/sadd Default daily activity file that holds the binary sampling data. dd are digits that represent the day of the month.
/usr/lib/sa/sa1 Shell script used to drive the sar data collection.
/usr/lib/sa/sa2 Shell script used to drive the sar data reporting.
