Batch file - loop ping - output to file hosts that are up -

i make .bat file loop below:

@echo off /l %%g in (1, 1, 69) (     ping -n 1 192.168.%%g.3      ping -n 1 192.168.%%g.4 ) 

then through output , send ips replied ping txt file. possible cmd batch file?

@echo off set output=%userprofile%\output.txt if exist "%output%" del "%output%" /l %%g in (1, 1, 69) (     call :ping 192.168.%%g.3     call :ping 192.168.%%g.4 ) goto :eof  :ping ping -n 1 %1 >nul && echo %1>>"%output%" 

basically, use && add command executed if previous command (the 1 before &&) completed (technically speaking, returned exit code of 0).

there's similar approach opposite case. if want perform actions on unsuccessful result of command, put || after , command implementing action.

edit

one note ping. notification router host not accessible. in case ping still exits 0 code ('successful'), because reply, if it's router , not actual host.

if can case hosts , don't want have such false positives in output file, you'll have parse output of ping keywords indicating whether pinging successful indeed. far can rely on lines showing aggregate stats: appear if reply intended host.

so, here's alternative approach:

@echo off set output=%userprofile%\output.txt if exist "%output%" del "%output%" /l %%g in (1, 1, 69) (     call :ping 192.168.%%g.3     call :ping 192.168.%%g.4 ) goto :eof  :ping ping -n 1 %1 | find "approximate round trip" >nul && echo %1>>"%output%"

changed both solutions use subroutine call in order avoid premature expansion of %ip% inside for loop. (could fixed enabling delayed expansion instead.)

also quoted %output% everywhere.
