Finding String in Variable Name

[Samir]

I need to search the variable COMPUTERNAME displayed by the SET command and then if my string is found, have it do X.

I know there's an easy way to do this, but it's late and I can't remember.

Any assistance?

Code: Select all

echo("%computername%"|find "text">nul && call x

Another option.

Code: Select all

If %COMPUTERNAME:MyString=% NEq %COMPUTERNAME% 'Do Something'

[Samir]

Thank you both so much!

Another option.

Code: Select all

If %COMPUTERNAME:MyString=% NEq %COMPUTERNAME% 'Do Something'

Where would I put my string in this command? "Mystring"? And then keep the equals after my search string?

[Samir]

One odd thing that I can't figure out. If I put either of these in a batch file (first line actually) with a "goto map" as the command at the end, all I get is a new instance of the command prompt under xp. Any ideas?

Helps to see all the code you are using. We are not omniscient.

Okay, here's the full batch for each version of the solution posted in this thread. Any assistance appreciated.

Code: Select all

echo("%computername%"|find "NEO">nul && GOTO MAP
:MAP
MAPS DRIVE
RUNS PROG
GOTO END
:NOMAP
RUNS PROG
:END

Code: Select all

If %COMPUTERNAME:NEO=% NEq %COMPUTERNAME% GOTO MAP
:MAP
MAPS DRIVE
RUNS PROG
GOTO END
:NOMAP
RUNS PROG
:END

Both results in the same odd result of a new command prompt just opening. I'm definitely puzzled as both search lines aren't anything special--just a find with an && and a if statement with a comparison.

This is still mostly pseudo code. If you are going to obfuscate the code and data don't expect to get an answer to your problem.

[Compo]

Code: Select all

If %COMPUTERNAME:NEO=% NEq %COMPUTERNAME% GOTO MAP
:MAP
MAPS DRIVE
RUNS PROG
GOTO END
:NOMAP
RUNS PROG
:END

If that really is the full batch then what's wrong with:

Code: Select all

If %COMPUTERNAME:NEO=% Equ %COMPUTERNAME% GOTO NOMAP
MAPS DRIVE
:NOMAP
RUNS PROG

[Squashman]

I agree Compo!

I can't post the exact code due to security reasons. I've revised it to this and everything works correctly.

Code: Select all

echo("%computername%"|find "NEO">nul && GOTO MAP
GOTO NOMAP
:MAP
ECHO MAP WORKING!
GOTO END
:NOMAP
ECHO NO MAP WORKING!
:END

I guess I'm on my own to figure out the rest.

[Samir]

Code: Select all

If %COMPUTERNAME:NEO=% NEq %COMPUTERNAME% GOTO MAP
:MAP
MAPS DRIVE
RUNS PROG
GOTO END
:NOMAP
RUNS PROG
:END

If that really is the full batch then what's wrong with:

Code: Select all

If %COMPUTERNAME:NEO=% Equ %COMPUTERNAME% GOTO NOMAP
MAPS DRIVE
:NOMAP
RUNS PROG

Thank you for the simplification of the algorithm. I'm going to use this simpler version.

MAPS DRIVE
:NOMAP
RUNS PROG

I spoke too soon. I forgot that the mapping must be undone after the program execution, hence the two branches. Right now I have this batch, but it's executing the map regardless. What may be wrong?

Code: Select all

@echo off
If %COMPUTERNAME:NEO=% NEq %COMPUTERNAME% GOTO MAP
:MAP
ECHO MAPS DRIVE
ECHO RUNS PROG
ECHO UNMAPS DRIVE
GOTO END
:NOMAP
ECHO RUNS PROG
:END
