Read 2 $vars from file line by line
Need some help with the following Bourne Shell script. The script is only looping one time and then stops. The script should loop as many times as there are entries in the input file = $FILE_LIST line by line. The file has the path to a source file and the destination directory where the file should be put. The script is transferring the files okay, now I want to make sure the entire file transferred using the chksum command, if so then delete the file off of server "B"
The FILE_LIST has the following data:
/home/test/test.pdf /home/test
/home/test/test.pdf /home/test
/home/test/servers_test /home/test
/home/test/test2842.pdf /home/test
/home/test/test.rpm /home/test
I would expect 5 lines of output, but my results is only giving me the first line. Here is the portion of the script that should delete the 5 files listed in the FILE_LIST file from server "B"
DID_NOT_TRANSFER=/tmp/FILES_DID_NOT_TRANSFER
FILE_LIST=/tmp/src_test
touch $DID_NOT_TRANSFER
while read SRC_FILES DEST_DIR
do
# Check to see if the entire file made it over using the cksum command
CHKSUMFTP=$(ssh test-ftp cksum $SRC_FILES |awk '{print $1}')
CHKSUMAPPS=$( cksum $DEST_DIR/`/usr/bin/basename $SRC_FILES`| awk '{print $1}')
# Check the value of the checksums from both servers
if [ "${CHKSUMFTP}" = "${CHKSUMAPPS}" ] ; then
ssh test-ftp /bin/rm ${SRC_FILES}
else # Save the file name in a temp file to be mailed out later
echo $SRC_FILES >> $DID_NOT_TRANSFER
echo " \n" >> $DID_NOT_TRANSFER
fi
done < $FILE_LIST
mailx -s "SRC_FILES did not transfer to apps properly on `date`" < $DID_NOT_TRANSFER maillist
/bin/rm $DID_NOT_TRANSFER
exit 0

SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-akq] [-t time] [file [command ...]]
DESCRIPTION
The script utility 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.
If the argument command is given, script will run the specified command with an optional argument vector instead of an interactive shell.
The following options are available:
-a Append the output to file or typescript, retaining the prior contents.
-k Log keys sent to program as well as output.
-q Run in quiet mode, omit the start and stop status messages.
-t time
Specify time interval between flushing script output file. A value of 0 causes script to flush for every character I/O event. The
default interval is 30 seconds.
The script ends when the forked shell (or command) 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. The script utility works best with commands that do not
manipulate the screen. The results are meant to emulate a hardcopy terminal, not an addressable one.
ENVIRONMENT
The following environment variable is utilized 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
The script utility places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
It is not possible to specify a command without also naming the script file because of argument parsing compatibility issues.
When running in -k mode, echo cancelling is far from ideal. The slave terminal mode is checked for ECHO mode to check when to avoid manual
echo logging. This does not work when in a raw mode where the program being run is doing manual echo.
