Use one button to go to a folder, and also delete all *.log?

Is it possible to use one button to go to a folder, and also delete all *.log file?


I have a button in the tool bar, the command is "cd c:\temp". When I click the button, the totalcmd would go to the directory c:\temp.

But I also want to delete all *.log file when I click the button. Is it possible?



Thank.

Jim

Hello, Jim.

I guess the following commandline should work

Code: Select all

cmd.exe /c "cd /d C:\temp & del *.log"

Cheers,

Thanks. It works.Perfect.

But it would be safer to do

Code: Select all

cmd.exe /c "del C:\temp\*.log"

instead, just for case when cd fails and del then deletes files from another directory.

You heard of errorlevel?

Code: Select all

cmd.exe /c "cd /d C:\temp & IF NOT ERRORLEVEL 1 (del *.log)"

milo1012,
Why are you doing 2 operations and check for error if one does completely the same thing?

BTW your command may be written in a shorter way:

Code: Select all

cd /d C:\temp && del *.log

Here && executes second command only if first one succeeded. Also || exists that does the opposite.

Anyway, my command is simpler and does what was asked.

...

Because that very syntax may be also used in a standalone batch file, and not just squeezed as a parameter to cmd.exe,
in case you want to swap the CD command with something else and need a check for errorlevel then.

You can use && and || in batch file too. cmd.exe /c processes simply a single batch line, with same rules applied.
Anyway, it is a bad style to mix multiple commands in a line, especially such as cd which affects next lines too.

And that is related to my previous answer, because...?
I just said that you can simply copy and paste common commands schemes that way, so that you may not have to have to think through every altered command.
BTW, with the errorcheck you can keep the batch open and output some message in case of errors.

By whose standard? There is no correct or wrong when it comes to multiple solutions for problems like the OP.

...especially such as cd which affects next lines too.

And other built-in things like mkdir and copy don't effect the next lines?
Most things in a batch may be effected by previous lines. We really shouldn't discuss platitudes here.
All solutions work.
