TSM Menu - Bash Shell Scripting

For years I have maintained a shell script on our jump server that was a menu for accessing all the TSM servers in our environment. It was a nice interface and great for noobies. It allowed for you to set your password and ID variables before the menu loaded so anyone could run the menu under their ID, then presented them with a nice menu to pick which TSM server they wished to access. It was nice and easy. The only problem was when servers were added or decommissioned. When that occurred I would then have to go out and revise the menu. This was a pain and soon to be more painful as we plan to add a lot more TSM servers in the near future. I remember seeing someone post that they had created a menu system based off of the dsm.sys file so I decided to write my own.

Ok, so the Before is more organized by region but as new servers come in I wanted the menu to update dynamically. So this new menu is built around the BASH shell's select menu function. The script pulls all the TSM server names from the dsm.sys and populates an array that the select statement reads and generates this menu. Make sure the variables the script declares work for you and your dsm.sys. My dsm.sys looks like this if I grep servername:

SERVERNAME         DTSM01          * Germany      LIB-MAN
SERVERNAME         DTSM02          * Germany             
SERVERNAME         DTSM03          * Germany             
SERVERNAME         DTSM20          * Germany      LIB-MAN
SERVERNAME         CTSM01          * Kings_Mnt    LIB-MAN
SERVERNAME         C1KDC2          * Kings_Mnt           
SERVERNAME         C1IF            * Kings_Mnt           
SERVERNAME         CTSM20          * Kings_Mnt           
SERVERNAME         CTSM30          * Kings_Mnt           
SERVERNAME         CTSM40          * Kings_Mnt           
SERVERNAME         CTSM46-Arch     * Kings_Mnt           
SERVERNAME         LUAX001         * Leonia       LIB-MAN
SERVERNAME         LUAX002         * Leonia              
SERVERNAME         LTSM01          * Leonia              
SERVERNAME         NTSM01          * Norcross     LIB-MAN
SERVERNAME         OUAX000         * Omaha        LIB-MAN
SERVERNAME         OUAX001         * Omaha               
SERVERNAME         OUAX003         * Omaha               
SErvername         OTSM01          * Omaha        LIB-MAN
SErvername         OTSM02          * Omaha               
SERVERNAME         PESTSM01        * PEST         LIB-MAN
SERVERNAME         PTSM01          * Tempe        LIB-MAN
SERVERNAME         PTSM02          * Tempe               
SERVERNAME         PTSM20          * Tempe               
SERVERNAME         PTSM25-Arch     * Tempe               
SERVERNAME         STSM01          * Singapore           
SERVERNAME         SIN01ZZ         * Singapore           

SERVERNAME         LABTSM                                

With the dsm.sys file formated this way I can use grep and awk to get specific data. This allows the script to build my menus according to my needs. Especially with the Cross Server sub menu that allows me to run a command across multiple servers at once. In the sub-menu it groups by distinct location which I placed in the servername line. Leave me a comment if you have any comments, questions, or suggestions.

See the script below:

#set -x
