OK pretty much know how manage a value hard coded in a variable in a shell script.

What I need is how do I get the value in file 1mo, or file 2mo, or file 3mo to become the value of the variable in the shell script.

> ls
> 1mo 2mo 3mo other files.

value of 1mo being XFG1mo.

Need to read the data in the file into the variable in the shell script.

OK found something that works.

for JUNK in $(cat ~/JTRMN | cut -f1 -dSmilie The smiley face here was trranslated from colon close paren. No space between -d and the colon.
do
export JTRMN=$JUNK
done

This reads an OS file named JTRMN.

The data read in is then exported as the value for env variable named JTRMN.

This works.

I appreciate the help.

Now I will edit the 17 backup scripts putting this read/export logic in them.
Each backup scripts will have its very own schedule file.
Most of the the "very own schedule files" will be softlinks to one of three actual files.
This gives me the ability to impact values passed - at this time - to 9, 6, or 2 backup scripts by simply changing the value in one of 3 files.

We login to the server under our UID.
We then sudo to a DBA service account who owns the various database instances.
I do keep a DBAs_readme.lst file documenting what each script does in the service account home directory.
Each script is documented.

So if my backup, my backup's backup, my backup's backup's backup, and I get hit with a bus, any DBA can be given access to the server will have a somewhat documented system to help them.
