How can I perform some commands on Intersystem cache from shellscript?

Question

I want to perform some commands on Intersystem cache from shell script. One solution which I know is through making a config file but the problem is I dont know how to use config file through shell script. Is there any other solution for this...

for example what I have to run on cache is

csession instancename
zn "area"
area>D ^%RI
Device:some/device/path
Next: It should take enter

This can be accomplished from a Linux shell, simply keep a log of the commands you need to perform and then put them into a script. Here's an example of logging into Cache and writing "Hello world" -- note that this also assumes you need to authenticate.

echo -e "username\npassword\nW \"Hello world\"\nH\n" | csession instance

Note that every command you would have run manually is in there and separated by "\n", this is the character that represents the "Enter" key.

It is possible (for some operating systems) to run the Cache terminal in batch mode. For example:

echo: off
wait for:Username
send: SYS<CR>
wait for:Password
send: XXX<CR>
echo: on

logfile: Somepath\myFile.log

send: ZN "AREA"
wait for:AREA>

send: D ^%RI
wait for:Device:
send: some/device/path
wait for:Next:
send: <CR>

This is documented in the Intersystems cache terminal documentation, especially the using terminal in batch mode section and the terminal scripts section.

I still didn't got it. I am new at shellscripting and cache – Ajit Nair May 29 '13 at 10:15
Did you read any of the documentation? What did you try? What don't you get? – psr May 29 '13 at 16:25

This is a very old question .. as I came across the same thing and so with a little R&D I found a work around to this problem. Which is very cool and simple.

Let's say I have this file (can be with any extension with each command in separate line)

myScript.scr

     zn "%SYS"
     for e="a","b","c" { w e,! }

So passing it to cache terminal in case of UNIX is using csession with linux PIPE (|) operator

cat myScript.scr | csession {instance_name}

Eg.

cat myScript.scr | csession CACHE

output

     a
     b
     c

Note:

• Don't separate a command in multiple lines else `csession` will through <SYNTAX> error. (See how I wrote the *for* loop)
• Extra knowledge - Intersystem Ensemble supports *Cache Terminal Batch Mode* in Windows case... While in linux there is no cterm to take the scripts.. 
• But linux gives you a work around to do this ;).

Hope this helps you guys!! cheers :D
