Command Logic
Hi,

I need the logic to utilize the command output to be feeded over to successive commands,

for example :

Code:
$ dtconf list-ls-data-sources -h hostname -P 636 -w ~/pwd.txt
DATA MASTER 1
DATA MASTER 2
DATA CONSUMER 1
DATA CONSUMER 1
DATA CONSUMER 1

Based on above output, i would like to utilize values like "DATA MASTER 1", "DATA MASTER 2".... in successive commands.

Is it possible to do one single command?

Thanks. JPrince

You could try:
Code:
dtconf list-ls-data-sources -h hostname -P 636 -w ~/pwd.txt |
while read val; do
  echo Try some command with "$val" 
done

Thanks for the reply.

However, I am getting the following error while running a test command :

$ ls | while read val ;echo Try some command with "$val" ; done
-bash: syntax error near unexpected token `done'[/CODE]

Please use code tags as required by forum rules!

If running into a "done", the shell expects to have encountered a "do" before. Read the man page of your shell!
Put a do in front of the read

Still getting the same error.

Code:
$ ls | while do read "val" ;echo Try some command with "$val" ; done
-bash: syntax error near unexpected token `do'

In your code, the "do" belongs just after the semicolon.

I corrected the left out "do" in my post...
