I have a text file with the following format:
name1:surname1
name2:surname2
name3:surname3
and so on.
I need to write a for loop in window batch script and assign to 2 variables
name=name1
surname=surname1
and so on. Something like (this is wrong)
for /F "tokens=*" %%row in (myfile.txt) do (
for /F "tokens=1* delims=:" %%u in ("%row%") do (
....
)
)
Any suggest?
You don't really need two nested loops for that.
What you probably will need, however, is delayed variable expansion.
@echo off
setlocal enabledelayedexpansion
for /f "tokens=1,2 delims=:" %%u in (myfile.txt) do (
set "name=%%u"
set "surname=%%v"
echo !surname!, !name!
)
outputs this for me:
surname1, name1
surname2, name2
surname3, name3
Delayed variable expansion is what allows you to assign the single-letter loop variables (u and v in this case) to real variables and use them in the rest of the loop, by accessing them with ! instead of %.
for /F "tokens=*" %%r in (myfile.txt) do (
for /F "tokens=1* delims=:" %%u in ("%%r") do (
....
)
)
or
for /F "tokens=1* delims=:" %%u in (myfile.txt) do (
....
)
Metavariables live r and u are limited to a single (case-sensitive) alphabetical character.
@echo off
setlocal EnableDelayedExpansion
for /F "tokens=1,2 delims=:" %%u in (myfile.txt) do (
set name=%%u
set surname=%%v
echo name=!name!
echo surname=!surname!
)
output:
name=name1
surname=surname1
name=name2
surname=surname2
name=name3
surname=surname3
