Shell Programming and Scripting

Hi,
The above solution has worked prefectly as expected....
Incase if i want to proceed with moving the files from Source to Target , only if the log file exits,if not do not do the archive but proceed with the next step in the script.
how can this be achived
Below is the orignal query that i am using:
I have used an "if condtion" to check the status of previous, however it always return 0.

Code:

find $LOGDIR -maxdepth 1 \( -name "*.log" -o -name "*.out" \) |
if [ $? != 0 ]; then
  echo "No Log Files to Achrive"
else
  while IFS="." read FILE
  do
    BASE=`basename "$FILE"`
    echo "$BASE" >/tmp/$$
    IFS="." read BASE EXT < /tmp/$$
    mv "$FILE" "$LOGARCHIVE/$BASE.$datetimestamp.$EXT"
    if [ $? != 0 ]
    then
      echo "! Error - Error archiving log file !"
    fi
  done
fi

Sorry, what? I don't think that translated very well.

Hi Corona688,

Sorry i could convey my message correctly......

In my query the "Find" is checking for files with ".log" and ".out" in the LOG_DIR,

I wanted to proceed with next steps only if the files exists.
If not exit from the while loop.

I tried checking with status of the previous command using if..but its not working.....

Please suggest.

So it should only move in/file.ext to out/file-date.ext when out/file-date.ext already exists?

If not that, then, when what already exists? The file you haven't moved yet? It already exists by definition...

if file.ext exits in Dir "in" then move it to out/file-date.ext.

else simply quit from the while loop....

find never prints nonexistent files. If find finds no files at all, it prints exactly nothing.

If the while read loop reads nothing the very first time, the code inside it won't run even once.

That's why your error-checking code doesn't report any errors -- there weren't any.

It's not useless, though. You might be unable to move the files for other reasons, like directory permissions.
