ECHO 在“真”条件下不工作

Question

Being a relative beginner, I can't figure this out. I have a script that is started via cron. Within this script is an if/fi where I check to see if a (yearly archive) directory does not exist. It it does not, I create the directory, and ATTEMPT to echo that to the cron's log file that is created for each run. The directory is created, but the echo does not appear in the log file.

Here is a snippet of the code in question.

035: yyyy=`date +%Y`
036: today=`date +%m/%d/%Y`
037: time=`date +%r` #+%l:%M:%S%P`
038: dayofweek=`date +%A`
039: numDayOfWeek=`date +%u`
040:
041: echo "Run Date/Time: $today $time"
042:
043: WFADIR="/data/ssa1/home1/NEI/GAP-EFT-FLAT/$yyyy"
044: if [ ! -d $WFADIR ] ; then
045:    mkdir /data/ssa1/home1/NEI/GAP-EFT-FLAT/$yyyy
046:    chmod 777 /data/ssa1/home1/NEI/GAP-EFT-FLAT/$yyyy
047:    echo ""
048:    echo "New folder $yyyy created in GAP-EFT-FLAT"
049: fi
050:
051: #display test variables for output
052: echo ""
053: echo "HOSTNAME..........: ${HOSTNAME^^}"
054: echo ""
055:

And here is the FULL log file.

As you can see, the echo from line 41 is in the log file. Then, as this was the first run for 2023, the 2023 directory did not yet exist. It WAS created and the permissions were changed as well, with lines 45 and 46, respectively.

drwxrwxrwx. 2 neiauto staff 61 Jan 3 08:00 2023

So why do lines 47 and 48 appear not to execute, and the next echo in the log file is from line 52, 53 and 54, with the hostname display, surrounded by blank lines?

I was expecting a blank line, and "New folder 2023 created in GAP-EFT-FLAT" to be echoed after the Run date/time (first) line of the log file, and before the host name display.

Answer 1

Very likely your directory already existed. Add an else echo $WFADIR already exists to your code to have your answer next year:-). My guess would be that the same code was run twice (on the same, or another host if shared disk-space was used).
