Need to substring something

[TheFuzz4]

Hey Guys,

First off you guys are such a great help with scripting and I greatly appreciate it.

Ok so here is what I am trying to do. I am in the process of writing a script. But I need to set one of the variables equal to a substring from another script. So here is what I need.

In my script I have a variable

ADMINPORT=

The = will be the result of cat otherscript | grep ADMIN_PORT

What I need though is not the admin port but the actual port that comes after that.
So if I run the command right now it will return the whole ADMIN_PORT=8011 but I just want the 8011.
Thanks for you help with this in advance.

Re: Need to substring something

well, in basic it would be:

right('ADMIN_PORT=8041', len('ADMIN_PORT=8041') - 11)

obviously you would replace 'ADMIN_PORT=8041' with whatever variable you are using in the script...and the syntax might be a little different depending on the language used. hopefully this will get you started in the right direction.

One option is to use use 'cut'

otherscript | grep ADMIN_PORT | cut -d= -f2

(-d= uses '=' as a field delimiter, and -f2 prints field number 2)

Hey thanks for both of those tips guys. I ended up using Kubicles suggestion and it worked like a charm. I love how with bash multiple ways to do something just depends on which way you decide to go.
