Removing Unnecessary Trailing Spaces

Imagine: we have a variable with some string data, and we have to remove unnecessary spaces from the end of this variable. The code below shows how to solve this problem:

@echo off
setlocal
set "a=111 222 "

:loop
set /a n+=1
for /f "tokens=%n%" %%i in ("%a%") do (
if not "%%i"=="" set b=%b%%%i && goto:loop
)

set a=%b:~0,-1%
set b=
echo "%a%"

Of course, you have to change this code a bit before using it. You can do it with the help of our award-winning batch files editor. Hope you'll find this example useful.

Copying Strings from One File to Another

The task to be discussed in this post looks very simple: copy some strings from a text file to another one. The file and the amount of strings are given. Here you can see the solution:

@echo off
setlocal enabledelayedexpansion
set "N=17"
set "count=0"
for /f "tokens=*" %%a in (first_file.txt) do (
if !count! GEQ !N! goto :EOF
echo %%a>>second_file.txt
set /a "count+=1"
)
But you can also try another version of this script. It will look like this (you should declare variables to run this script):
set count=0
for /f "skip=2 tokens=*" %%a in (%file_name%) do (
set /a count=!count!+1
if /i !count! leq N echo %%a>>new.txt
)
Hope you'll find these scripts useful.

Adding Quotes to Lines in Text

Let's discuss quite a simple task today. Imagine: you need to change each line in a text file by adding quotes to it. I mean you want to get from list like listitem1, listitem2, listitem3... list like "listitem1", "listitem2", "listitem3". This is quite a simple task, and the script solution looks like this:

@echo off
for /f "usebackq tokens=*" %%c in ("about.txt") do (
echo "%%c",>> about1.txt
)
As far as you can see, it's not difficult to write this script with help of our award-winning batch files editor. Hope you'll find this small example useful.
