65} How do I add text in front and after each line in a text file?
Assume the following LFN-type test file: "My test file.txt"
line 1
line 2 &()[]{}^=;!'+,`~
line 3 <>
line 4
line 6 Line 5 is empty!
With pure script, but skipping any empty lines!
@echo off & setlocal enableextensions
for /f "delims=" %%r in ('type "My test file.txt"') do (
echo Add in front%%radd after)
endlocal & goto :EOF
The output will be
Add in frontline 1add after
Add in frontline 2 &()[]{}^=;!'+,`~add after
Add in frontline 3 <>add after
Add in frontline 4add after
Add in frontline 6 Line 5 is empty!add after
Note how this at the same time answers the question how to remove
empty lines from a text file.
With SED
@echo off & setlocal enableextensions
<"My test file.txt" sed -e "s/.*/Add in front
&add after/"
endlocal & goto :EOF
The output will be
Add in frontline 1add after
Add in frontline 2 &()[]{}^=;!'+,`~add after
Add in frontline 3 <>add after
Add in frontline 4add after
Add in frontadd after
Add in frontline 6 Line 5 is empty!add after
