Hey all, i have a PRETTY basic batch file scripting question.

i have a bat file and i need to remove a part of it, preferebly automatically with another bat file. here is the before and after i would like (this is just the one line i need edited from a batch file, not the whole batch)

entry in file1.bat:

net use \\uncpathtoserver /user:[emailprotected] *

desired outcome after RUNNING batch file:

net use \\uncpathtoserver /user:example *

Basically i am trying to remove the @domain.com part. I have been USING an older version of samba that let me use full email address for my username, and the newer versions of samba dont like it, so i need to change that in a number of user's scripts. We are not on an active directory system, which is why i have the scripts in the first place.

thanks in advance for the help.Why not just copy all the scripts to another directory, then edit all of those.
Yes, you could automate the process, but why?
If a string has exactly one @ character, you could remove it by splitting the string into tokens using @ as the delimiter.

This is before.bat

@echo off
REM Comment 1
net use \\uncpathtoserver1 /user:[emailprotected] *
REM Comment 2
net use \\uncpathtoserver2 /user:[emailprotected] *
REM Comment 3
net use \\uncpathtoserver3 /user:[emailprotected] *
REM Comment 4
net use \\uncpathtoserver4 /user:[emailprotected] *

This script I call transform.bat. It assumes

(1) The script to be transformed has @echo off as the first line. That line will be skipped and a new one output at the start of processing.
(2) Only lines STARTING "net use" will have @ symbols

@echo off
echo @echo off
for /f "skip=1 usebackq tokens=1* [emailprotected]" %%A in ("%1") do echo %%A | find /i "net use">nul && (echo %%A *) || (echo %%A)

usage:

transform.bat "before.bat" > "after.bat"

after.bat

@echo off
REM Comment 1
net use \\uncpathtoserver1 /user:user1 *
REM Comment 2
net use \\uncpathtoserver2 /user:user2 *
REM Comment 3
net use \\uncpathtoserver3 /user:user3 *
REM Comment 4
net use \\uncpathtoserver4 /user:user4 *




Salmon, Worked Like a Charm!

Thanks a tonok, maybe not like a charm. I noticed a few issues with the output. maybe if i put the whole script it will be easier to see

orig script:

@echo off
color b0
title Map Network Drives Script
net use * /delete
rem Map network drives
cls
echo Please enter your E-MAIL password
net use \\uncpathtoserver /user:[emailprotected] *
net use T: \\uncpathtoserver\share1 /persistent:yes
net use U: \\uncpathtoserver\share2 /persistent:yes
net use n: \\uncpathtoserver\share3 /persistent:yes
rem Show drives
cls
net use
pause
Press any key to continue . . . .

When i run the script i get the FOLLOWING:

@echo off
color b0
title Map Network Drives Script
net use * /delete *
rem Map network drives
cls
echo Please enter your E-MAIL password
net use \\uncpathtoserver /user:username *
net use T: \\uncpathtoserver\share1 /persistent:yes *
net use U: \\uncpathtoserver\share2 /persistent:yes *
net use n: \\uncpathtoserver\share3 /persistent:yes *
rem Show drives
cls
net use *
pause
Press any key to continue . . . .


When what i need to be getting is:

@echo off
color b0
title Map Network Drives Script
net use * /delete
rem Map network drives
cls
echo Please enter your E-MAIL password
net use \\uncpathtoserver /user:username *
net use T: \\uncpathtoserver\share1 /persistent:yes
net use U: \\uncpathtoserver\share2 /persistent:yes
net use n: \\uncpathtoserver\share3 /persistent:yes
rem Show drives
cls
net use
pause
Press any key to continue . . . .

Notice the extra *,s and spaces?Try this

@echo off
echo @echo off
for /f "skip=1 usebackq tokens=1* [emailprotected]" %%A in ("%1") do echo %%A | find /i "net use \\">nul && (echo %%A *) || (echo %%A)

Result

@echo off
color b0
title Map Network Drives Script
net use * /delete
rem Map network drives
cls
echo Please enter your E-MAIL password
net use \\uncpathtoserver /user:username *
net use T: \\uncpathtoserver\share1 /persistent:yes
net use U: \\uncpathtoserver\share2 /persistent:yes
net use n: \\uncpathtoserver\share3 /persistent:yes
rem Show drives
cls
net use
pause
Press any key to continue . . . .



Success!

Thanks a ton
