Trimming a text file from right to left till special character

[sumiRoot]

Hey Friends,

I have a text file name as abc.txt and the data reside as below:

Computer hope/abc/file_name.xml
Computer hope/abc/file_name2.xml
Hope Computer/def/file_name3.xml
....

So now i want the trimmed data from the abc.txt file to new file named as def.txt

file_name.xml
file_name2.xml
file_name3.xml

Can you please help me in this, can we create batch file for this ?

I have tried searching online but get it below code but not what i want.

@ECHO off
cls
setlocal enableextensions enabledelayedexpansion
set num=15 ::trimmed letters
set /a num=%num%+1

for /f "tokens=* delims= " %%f in (abc.txt) do (   
set a=%%f
echo !a:~0,%num%!
echo !a:~0,%num%! >>def.txt
)
pause

Thanks,
hope to hear back from you soon.

As long as the strings are in the form of file paths, you can use the %~nx syntax for FOR variables, which returns the name, dot, and extension, and was designed for this purpose:

Code: [Select]

@echo off
if exist def.txt del def.txt
for /f "delims=" %%A in (abc.txt) do (
        echo %%~nxA >> def.txt
        )
abc.txt

Code: [Select]

Computer hope/abc/file_name.xml
Computer hope/abc/file_name2.xml
Hope Computer/def/file_name3.xml
def.txt

Code: [Select]

file_name.xml
file_name2.xml
file_name3.xml

And the syntax that Salmon Trout has shown is well documented in the help file for the `FOR` command.

Code: [Select]

In addition, substitution of FOR variable references has been enhanced.
You can now use the following optional syntax:

    %~I         - expands %I removing any surrounding quotes (")
    %~fI        - expands %I to a fully qualified path name
    %~dI        - expands %I to a drive letter only
    %~pI        - expands %I to a path only
    %~nI        - expands %I to a file name only
    %~xI        - expands %I to a file extension only
    %~sI        - expanded path contains short names only
    %~aI        - expands %I to file attributes of file
    %~tI        - expands %I to date/time of file
    %~zI        - expands %I to size of file

Thanks for your help Salmon Trout, it solved my problem.
Thanks Squashman for your syntax in For clause.

Thanks Squashman for your syntax in For clause.

It's not my syntax.  That is from the help file for the FOR command.
