command line text processing..

[Jim Carter]

Hi all,

I am on Windows:

I have a customozed command "lsdesktops" (I mean when I run C:\>
lsdesktops at cmd prompt) and it gives an output like below:
--------------------------------------
TEST-MACHINE1:Windows SP3 Memory
TEST-MACHINE2:Windows SP1 Processor
TEST-MACHINE3:Windows SP4 Configuration
......... ###and many more lines like the above three lines
---------------------------------------

Now I need a commmand line perl code to strip off every thing that
starts after colon (inlcuding colon).
Ex: The output should be

-------------------
TEST-MACHINE1
TEST-MACHINE2
TEST-MACHINE3
TEST-MACHINE4
TEST-MACHINE5
TEST-MACHINE6
......
......
---------------------


I know I need to use -e option and reg expression, but is not giving
me the exact result.

Thanks,
JCarter

Show us your code so we know what it did right/wrong.

lsdesktops | perl -F: -lane "print $F[0]"
