Get PID from port

[Docfxit]

I have a syntax error when trying to get the PID from a port number:

Code: Select all

for /f "tokens=5" %a in ('netstat -aon ^| findstr 80') do tasklist /FI "PID eq %a"

Code: Select all

a" was unexpected at this time.

Thanks,

I suspect it's because of the FOR variables. In a batch script you have to double the percent signs.

That fixed the error really great.

Do you have any idea why the port isn't being substituted in this code?

Code: Select all

set "Port#=80"
for /f "tokens=5" %%a in ('netstat -aon ^| findstr %Port#%') do tasklist /FI "PID eq %%a"

Thank you,

I don't know what you are expecting. First of all you should enclose the search string into quotes for the findstr command. And instead of "80" you should rather look for ":80\>" where \> marks the right word boundary as explained in the help of findstr. For your command that would mean
findstr ":%Port#%\>"

You used it correctly in previous questions you have asked on the forums.

Eighth line of the help file for the FOR command.
To use the FOR command in a batch program, specify %%variable instead
of %variable. Variable names are case sensitive, so %i is different
from %I.
