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,

SCRIPT(1) BSD General Commands Manual SCRIPT(1)NAME
script -- make typescript of terminal session
SYNOPSIS
script [-adfpqr] [-c command] [file]
DESCRIPTION
script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Option:
-a Append the output to file or typescript, retaining the prior contents.
-c command
Run the named command instead of the shell. Useful for capturing the output of a program that behaves differently when associated
with a tty.
-d When playing back a session with the -p flag, don't sleep between records when playing back a timestamped session.
-f Flush output after each write. This is useful for watching the script output in real time.
-p Play back a session recorded with the -r flag in real time.
-q Be quiet, and don't output started and ended lines.
-r Record a session with input, output, and timestamping.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is used by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO csh(1) (for the history mechanism).
HISTORY
The script command appeared in 3.0BSD.
BUGS
script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
