Title: hostname in batch file
Post by: 037 on March 31, 2010, 07:06:40 AM

how can i get the hostname from a workstation and make a folder named the same as the workstation? i have tried "setlocal, set hostname=%hostname%, endlocal".

or in other words, "hostname" is a command. how can i make a file from the output of a command?

xpp sp3.

i am trying to backup multiple folders to one folder with the name of the workstation it came from.

Im assuming you mean appending to a file, when you say "make a file from the output of a command"

> Clears the file
>> adds a line to a file

example:
echo hello>>myfile.txt

i am trying to go to a workstation and run my batchfile. it needs to find the computer name and make a file with the name of the workstation. then it will backup some folders and save them under the folder that it just created with the computer name so i can find it later to restore them. i have the batch file created and it can store folders under the %username% variable, but i would much rather have it store under computer name.

example: when i type "echo %username%" in a cmd it displays my user name. but when i type "echo %hostname%" it does not display. i can however type "hostname" by itself to get the workstation name....

thanks in advance...

ComputerName is a system variable that you can use:

md %computername%

OR

You can still use the hostname command in a batch file:

Code: [Select]

@echo off
for /f %%a in ('hostname') do (
  md %%a
) 

Good luck.  8)

Env works on WinXP but you can also use set to list all the environment variables.

@echo off
md c:\%computername%

or if you want to name a file:

@echo off
echo. >> c:\%computername%.txt

"Hostname" is a command. How can I make a file from the output of a command?

C:\>type  thirty7.bat

Code: [Select]

@echo off

hostname  >  host.txt

type host.txt

pause
md Okie
cd Okie

echo hello okie > host.txt

type host.txt
Output:

C:\>thirty7.bat
Okie
Press any key to continue . . .
hello okie

C:\Okie>
