Creating *.bat file?

Question

cmd/bat

Tell me how to make a check in the file:
There is a xxx.log file larger than 10 MB. at the very end there should be a line “Everything is Ok”, how to check this line, if it exists, then execute the command such and such, if not, then exit the script.
OS: Windows

Answer 1

$lastline = gcxxx.log | select -last 1
if ($lastline -eq "Everything is Ok") {write-host Wheee!}
PowerShell

Answer 2

I can't resist :) GREPs, PowerShells are unsportsmanlike.
Slow version using pure batch:

for /f "delims=" %%a in (build.xml) do set lastLine="%%a"
if %lastLine%=="Everything is Ok" echo YEAH!

True, it will only work under some Windows not younger than XP.

Answer 3

Maybe it's better to do it with PowerShell?

Answer 4

I think the %ERRORLEVEL% variable will help you.
If the desired combination is found in the file, the variable will return "0", otherwise "1".
For example:
find "Everything is Ok" <D:\filename.log
if %ERRORLEVEL%==1 start start.cmd
if %ERRORLEVEL%==1 pause
If the line is found, start.cmd will be executed if there is no such line in the file, the script will wait for any key to be pressed.

Answer 5

Slash in the path to the file beguiled)

@echo off
findstr "Everything is Ok" d:/test.txt >null
if errorlevel 1 GOTO EXIT
:COMMAND
echo
echo "Whoooohoo!"
:EXIT
exit 0

Answer 6

findstr "Everything is Ok" c:\path\to\logfile.log

Answer 7

@echo off
for /F %%I in ('"find /n /i "everything is ok" file.txt | cut -f 1 -d ] | cut -f 2 -d ["') do SET Number=%%I 2>nul
For /F "Tokens=3" %%A In ('Find /V /C "" file.txt') Do Set sCount=%%A 
If %sCount% GEQ %Number% Echo whoohoo

something like this. grep has sparks, the cut utility can be taken from cygwin for example
