In windows it is possible to write a batch that emulates findstr / n / r. file.txt?
Okay, I know this is purely academic because the team findstr
can do what I expect in jiffy.
I have a text file whose lines (lines) I want to number. I was wondering if it was possible to write a batch that mimics it and gives me the flexibility to move the chain of labels anywhere in the line.
For example standard output 1: some string
Let's say I want
-
1)some string
(without using find and replace in Windows Explorer) or -
somestring........(1)
, or -
s 1] somestring

EDIT : I changed the code to insert the line number anywhere in the line:
@echo off
setlocal DisableDelayedExpansion
rem Define the format of output lines; for example
rem To show "(lineNo) line" use:
set "format=(!lineNo!) !line!"
rem To show "20 chars of line (lineNo) rest of line" use:
set "format=!line:~0,20! (!lineNo!) !line:~20!"
rem and adjust each line read appending 20 spaces
rem To show "line (lineNo placed at column 75)" use:
set "format=!line:~0,73! (!lineNo!)"
rem and adjust each line read appending 73 spaces
rem To show line numbers with left zeros, start lineNo with the proper
rem number of zeros and modify the format accordingly; for example:
set lineNo=100
set "format=!line:~0,73! (!lineNo:~1!)"
setlocal EnableDelayedExpansion
copy %1 "%~1.tmp" > NUL
set "EOF=%random%%random%%random%"
echo :%EOF%EOF:>> "%~1.tmp"
REM set lineNo=0
call :ReadLines < "%~1.tmp"
del "%~1.tmp"
goto :EOF
:ReadLines
set "line="
set /P "line="
if "!line!" equ ":%EOF%EOF:" goto :EOF
set "line=!line! "
set /A lineNo+=1
echo %format%
goto ReadLines
Output example:
@echo off (01)
setlocal DisableDelayedExpansion (02)
(03)
rem Define the format of output lines; for example (04)
(05)
rem To show "(lineNo) line" use: (06)
set "format=(!lineNo!) !line!" (07)
(08)
rem To show "20 chars of line (lineNo) rest of line" use: (09)
set "format=!line:~0,20! (!lineNo!) !line:~20!" (10)
rem and adjust each line read appending 20 spaces (11)
(12)
rem To show "line (lineNo placed at column 75)" use: (13)
set "format=!line:~0,73! (!lineNo!)" (14)
rem and adjust each line read appending 73 spaces (15)
(16)
rem To show line numbers with left zeros, start lineNo with the proper (17)
rem number of zeros and modify the format accordingly; for example: (18)
set lineNo=100 (19)
set "format=!line:~0,73! (!lineNo:~1!)" (20)
(21)
(22)
setlocal EnableDelayedExpansion (23)
copy %1 "%~1.tmp" > NUL (24)
set "EOF=%random%%random%%random%" (25)
echo :%EOF%EOF:>> "%~1.tmp" (26)
REM set lineNo=0 (27)
call :ReadLines < "%~1.tmp" (28)
del "%~1.tmp" (29)
goto :EOF (30)
(31)
:ReadLines (32)
set "line=" (33)
set /P "line=" (34)
if "!line!" equ ":%EOF%EOF:" goto :EOF (35)
set "line=!line! (36)
set /A lineNo+=1 (37)
echo %format% (38)
goto ReadLines (39)

@echo off
SET SNO=1
FOR /f "tokens=*" %%X IN (friends.txt) DO (call :subroutine %%X)
GOTO :eof
:subroutine
:: This is the interesting part where the value of the SNO can be
:: moved around.If you want the SNO bang in the middle then
:: then that that another project ! Moreover moving it to the end
:: is problematic if the strings don't have the same number

echo.
echo (%SNO%) %1>>numbered.txt
set /a SNO+=1
GOTO :eof
