Getting exit status code from 'ftp' command in linux shell

Question

I need to retrive the exit status code from a command line program. No worries, I used $?. But for ftp, even if it doesn\'t connect, it opens the ftp shell, so I\'m not able

Try the following scripts.

To copy:

#!/bin/bash
# cftp.sh
# set -x

FTPSERVER="$1"
FTPPORT="$2"
REMOTEDIR="$3"

[[ "$REMOTEDIR" ]] || { echo -e "Usage: $0    [file1] [file2] ..." > /dev/stderr ; exit 1 ; }

L=$((BASH_ARGC-3))

LOCALFILES=("${BASH_ARGV[@]:0:$L}")

RETCODE=0

for LOCALFILE in "${LOCALFILES[@]}"
do
  THISRETCODE=0
  [[ -f "$LOCALFILE" ]] || THISRETCODE=1

  LOCALDIR="$(dirname "$LOCALFILE")"
  LOCALFILENAME="$(basename "$LOCALFILE")"

  [[ $THISRETCODE = 0 ]] &&
  /usr/bin/ftp -iv "$FTPSERVER" << EOF | grep -q '226 Transfer complete' || THISRETCODE=1
    lcd $LOCALDIR
    cd $REMOTEDIR
    put $LOCALFILENAME
EOF

  RETCODE=$((RETCODE+THISRETCODE))
done

exit $RETCODE

To move:

#!/bin/bash
# mftp.sh
# set -x

FTPSERVER="$1"
FTPPORT="$2"
REMOTEDIR="$3"

[[ "$REMOTEDIR" ]] || { echo -e "Usage: $0    [file1] [file2] ..." > /dev/stderr ; exit 1 ; }

L=$((BASH_ARGC-3))

LOCALFILES=("${BASH_ARGV[@]:0:$L}")

RETCODE=0

for LOCALFILE in "${LOCALFILES[@]}"
do
  THISRETCODE=0
  [[ -f "$LOCALFILE" ]] || THISRETCODE=1

  LOCALDIR="$(dirname "$LOCALFILE")"
  LOCALFILENAME="$(basename "$LOCALFILE")"

  [[ $THISRETCODE = 0 ]] &&
  /usr/bin/ftp -iv "$FTPSERVER" << EOF | grep -q '226 Transfer complete' || THISRETCODE=1
    lcd $LOCALDIR
    cd $REMOTEDIR
    put $LOCALFILENAME
EOF

  [[ $THISRETCODE = 0 ]] &&
  /bin/rm -f "$LOCALFILE" || THISRETCODE=1

  RETCODE=$((RETCODE+THISRETCODE))
done

exit $RETCODE

Here are some test cases:

For copying.

$ ./cftp.sh ; echo return code: $?
Usage: ./cftp.sh    [file1] [file2] ...
return code: 1
$ ./cftp.sh ftpserver 21 /mnt/disk4/d0/test ; echo return code: $?
return code: 0
$ ./cftp.sh ftpserver 21 /mnt/disk4/d0/test cftp.sh mftp.sh ; echo return code: $?
return code: 0
$ ./cftp.sh ftpserver 21 /mnt/disk4/d0/test *ftp.sh ; echo return code: $?
return code: 0
$ ./cftp.sh ftpserver 21 /mnt/disk4/d0/test cftp.s ; echo return code: $?
return code: 1
$ ./cftp.sh ftpserver 21 /mnt/disk4/d0/test cftp.s mftp.s ; echo return code: $?
return code: 2
$ ./cftp.sh ftpserver 21 /mnt/disk4/d0/tes cftp.sh ; echo return code: $?
return code: 1

For moving.

$ ./mftp.sh ftpserver 21 /mnt/disk4/d0/test cftp.sh ; echo return code: $?
/bin/rm: cannot remove `cftp.sh': Permission denied
return code: 1
$ echo foo > /tmp/bar
$ ./mftp.sh ftpserver 21 /mnt/disk4/d0/test /tmp/bar ; echo return code: $?
return code: 0
$ ls -lha /tmp/bar
ls: cannot access /tmp/bar: No such file or directory
