UNIX for Dummies Questions & Answers

I created file called "tape_name" which contains

tape_mon_A="TAPE_MON_A"
tape_tue_A="TAPE_TUE_A"
tape_wed_A="TAPE_WED_A"
tape_thr_A="TAPE_THR_A"
tape_mon_B="TAPE_MON_B"
tape_tue_B="TAPE_TUE_B"
tape_wed_B="TAPE_WED_B"
tape_thr_B="TAPE_THR_B"


I created test script as follow

#!/bin/sh

TAPE_LOC="location/of/the/above/file"
. /$TAPE_LOC/tape_name

echo "$tape_mon_A"

echo "$tape_tue_A"


when I run above script it returnes

TAPE_MON_A
TAPE_TUE_A

=============

Question is I don't want to hard code omnib command with tape name since it changes frequently.

my regular tape_name hardcoded commands run without any problem

sudo -u root /usr/bin/rsh domain.server.com "/opt/omni/bin/omnib -datalist TUE_TAPE-TST -mode full -load high

but when I changed TUE_TAPE-TST to $TAPE_BACKUP variable the command is not working.


Is there way to make TUE_TAPE-TST to accept variable parameter as I tried on test script?


thank you

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

You don't want to hardcode, that's ok.
But wouldn't it be more helpful if you'd just check which day today is ie. with the Unix week day like:

Code:

date +%w
5

where it's output number is read as following

Code:

1 = monday
2 = tuesday
3 = wednesday
4 = thursday
5 = friday
6 = saturday
0 = sunday

You could check which day it is and then decide in a case construct for example which tape to use.

Why should it work? In your excerpts I can't see any definition of $TAPE_BACKUP.

The whole thing could be automated, including your sudo and backup commands. As said, I would try to get the current date 1st and then decide by this which tape to use.

When I run following command

Code:

#!/bin/sh

TAPE_LIST="usr/local/bin/archbakTST/BACKUP_TAPES"
. /$TAPE_LIST

echo "sudo -u root /usr/bin/rsh remote.server.com /opt/omni/bin/omnib -datalist "$tape_test_TEST" -mode full -lo
ad high"

Return is

Code:

sudo -u root /usr/bin/rsh remote.server.com /opt/omni/bin/omnib -datalist  -mode full -load high

and is missing

Code:

sudo -u root /usr/bin/rsh remote.server.com /opt/omni/bin/omnib -datalist [missing parameter here] -mode full -load high

and $tape_test_TEST is from following file which contains one line of datalist called "TESTDB3-TEST"

BACKUP_TAPES:

Code:

tape_test_TEST="TESTDB3-TEST"

Not sure why it is not working. Try if a very simple example works and might want to use different #shebang with bash or ksh just to make sure:

Code:

$> cat parm
VAR=123
$> cat mach.ksh
#!/usr/bin/ksh

. ./parm
echo $VAR
$> ./mach.ksh
123

Thank you! I found the mistakes on my script.
