The Environmental Variable TMSSCMDSTRING changes the behavior of Command Line Programs to take the value set in TMSSCMDSTRING and write that string, along with the variables to stdout.

This allows you to write commands automatically using the value TMSSCMDSTRING along with the values contained in the output from the Command Line Programs.

Using TMSS10MoveList output as an example, the standard output displays Volume-ID, Current and Target Repositories as well as move times and attributes.

When the Variable TMSSCMDSTRING is set before the execution of the Command Line Utilities (in this example TMSS10MoveList) it modifies the output from the standard report, to that of a custom string that can include output variables.

Setting TMSSCMDSTRING to create an ejection script for a TSM instance, listing all Volume-ID's that need to be ejected for processing and transport to the Vault.

set TMSSCMDSTRING=checkout libvol DC1_LIB0 $volume-id checklabel=yes remove=yes

When TMSS10MoveList is executed, the output will print out the assigned string, exchanging the variable $volume-id with the current Volume-ID.

The resulting output will now be:

checkout libvol DC1_LIB0 210498L6 checklabel=yes remove=yes
checkout libvol DC1_LIB0 210701L6 checklabel=yes remove=yes
checkout libvol DC1_LIB0 210959L6 checklabel=yes remove=yes
checkout libvol DC1_LIB0 211049L6 checklabel=yes remove=yes

Variables available include:

• $customer-id
• $media-id
• $volume-id
