Lightbulb Help with Backup Shell Script 'ksh + awk over ssh'
Hi

newbeeeee alarm

i want to send a little script over ssh
this script mus download a report.tar then rename and move. the report name format is report_<host.with.dot>-10-09-20-11:55:25.tar

Code:
function remote_cmd_mv
{
  _host=$1

  ARCHROOTDIR='/tmp'
  ARCHMOVED="$ARCHROOTDIR/report_moved"
  LS_REPM='{lo -altr report_*.tar | awk -F" " '{print $9}'}'
  MV_NAME='{ echo ${LS_REPM} | awk -F"." '{print $1"." $2"." $3"." $4"." $5"." "tar_moved"}' }'


  cmd_string="cd \/tmp \
      for list in ${LS_REPM}; do ${list} ${ARCHMOVED}\/${MV_NAME}; done \
      cd - ; \
  "

  remote_cmd "${_host}" "${cmd_string}" ; ret_val=$? ;
}

error:
Code:
bash-3.00$ ksh script.ksh
script.ksh[69]: syntax error at line 108 : `"

  remote_cmd "${_host}" "$cmd_string" ; ret_val=$?
}

function remote_cmd_cp_str
{
  _host=$1

  ARCHROOTDIR="/tmp"
  ARCHMOVED="$ARCHROOTDIR/report_moved"
  LS_REPC='ls -1tr /tmp/report_* | tail -1'
  echo $LS_REPC

  cmd_string="${LS_REPC}"

  remote_cmd_cp "${_host}" "$cmd_string" ; ret_val=$? ;
}

function remote_cmd_mv
{
  _host=$1

  ARCHROOTDIR='/tmp'
  ARCHMOVED="$ARCHROOTDIR/report_moved"
  LS_REPM='{lo -altr report_*.tar | awk -F"' unexpected

bash-3.00$

You probably have some backtick-construct open, which isn't closed properly. Look from your line 108 backwards for something like

Code:
variable=`somecommand ...

instead of

Code:
variable=`somecommand ... `

Notice the rightmost "`" in the second variant.

Furthermore, you shouldn't use backticks any more, as their usage is discouraged and the whole language construct works only for purposes of backward-compatibility. Use "$(...)" instead:

Code:
old:     variable=`somecommand | othercommand`
correct: variable=$(somecommand | othercommand)

This is easier to read, less error-prone and even usable recursively:

Code:
var=$(sub-shell-level-1 | command "$(sub-shell-level-2)")

I hope this helps.

hmm...

The "script.ksh[69]" looks like the real error is in line 69. This means NOT the line number of the file the script resides in, but the 69th line of the main() routine of script.ksh. Once several functions reside in one file interpreting the line numbers becomes quite tricky.

As you haven't posted your complete script so far it is quite impossible for me to find out where the problem is - the code you posted seems to be correct as fas as i could see.

To further investigate issue at the start of your script a "set -xv" (don't forget to unset via "set +xv" at the end) and call your script this way:

Code:
script.ksh 2>&1 | more

I hope this helps.
