I need batch commnad to findstr and retrieve text to the end of text file.

text file include

  #  failure         detail                           
                                                      
 1.  AssertionError  Response time is less than 100ms 
                     expected false to be truthy      
                     at assertion:1 in test-script    
                     inside "epos-agentDetailsInfo"   
   
 2.  AssertionError  Response time is less than 100ms 
                     expected false to be truthy      
                     at assertion:1 in test-script    
                     inside "epos-getccounts"

I need to find "AssertionError" and retrieve text to the end of text file.

I expect to show since "AssertionError" untill the end of file.

I try this.

@echo off
setlocal
for /F "tokens=* delims=" %%a in ('findstr /I "AssertionError" test1.log') do set "uniuser=%%a"  
echo User is: %uniuser%   

endlocal

and it 's show only " 2. AssertionError Response time is less than 100ms"

CodePudding user response：

I believe that this is what you need:

It's not clear whether the empty lines in your data are actually empty, or contain one, two, or more spaces. The code caters for any pf these situations.

@ECHO OFF
SETLOCAL
rem The following settings for the source directory and filenames are names
rem that I use for testing and deliberately include names which include spaces to make sure
rem that the process works using such names. These will need to be changed to suit your situation.

SET "sourcedir=u:\your files"
SET "filename1=%sourcedir%\q74454843.txt"
SET "outfile=%sourcedir%\q74454843.rpt"

SET "repro="

(
FOR /f "tokens=1*delims=]" %%b IN ('find /n /v "" ^<"%filename1%"') DO (
 SET "mtline=%%c"
 IF DEFINED mtline CALL SET "mtline=%%mtline: =%%"
 IF DEFINED mtline (
  IF DEFINED repro (
   ECHO %%c
  ) ELSE (
   ECHO %%c|FINDSTR /L /C:"AssertionError" >NUL
   IF NOT ERRORLEVEL 1 (SET "repro=Y"&ECHO %%c)
  )
 ) ELSE (
 IF DEFINED repro ECHO.
 SET "repro="
 )
)
)>"%outfile%"

GOTO :EOF

repro is a flag to determine whether to reproduce the line or not.

Each line is numbered with a leading [linenumber] by the find so the part before the ] is assigned to %%b and the actual line contents to %%c.

mtline is then used as substringing metavariables (like %%c) is not supported; it receives a copy of %%c and if this is not empty, removes any spaces.

if mtline is then empty, batch interprets it as undefined.

if mtline is defined, the code then determines whether repro is defined and echoes %%c if it is defined, otherwise it asks findstr whether the line contains the target string; if it does, then set repro to a value (making it defined and echo the line.

if mtline is not defined, then we have reached the end of the section, so echo an empty line and clear repro so no further lines are reproduced.

The ^< is an escaped redirector which tells cmd that the redirector is part of the find command, not the for.

The entire for command is enclosed in parentheses so that the echoes it executes can be redirected to a file.
