Use 1 variable for all tokens in for-loop
Posted: 01 Jun 2020 09:01
My apologies if this has been asked before.
'input.txt':
When you open 'input.txt' (with every string on a new line) in a for-loop (directly, or through a command), it will use the same %A for each line, as expected:
When using a variable on the other hand, and despite <space> being a default delimiter, you'd have to use tokens and another variable for every token, which I find very strange:
In Bash a <space> is also a delimiter by default, but the same variable is used for each token, as expected:
Is this "trick"...
...the only way to do that in CMD/Batch?
'input.txt':
Code: Select all
test1
test2
test3Code: Select all
FOR /F %A IN (input.txt) DO @ECHO -%A
-test1
-test2
-test3
FOR /F %A IN ('TYPE input.txt') DO @ECHO -%A
-test1
-test2
-test3Code: Select all
SET str=test1 test2 test3
FOR /F "tokens=1-3" %A IN ("%str%") DO @(
More? ECHO -%A
More? ECHO -%B
More? ECHO -%C
More? )
-test1
-test2
-test3Code: Select all
str="test1 test2 test3"
for a in $str; do echo -$a; done
-test1
-test2
-test3Code: Select all
SET str=test1 test2 test3
FOR /F %A IN ('ECHO.%str: =^&ECHO.%') DO @ECHO -%A
-test1
-test2
-test3
