Hello Again! Below is my revised code for trimming whitespace from the start and end of a string: @echo off & setlocal enableextensions disabledelayedexpansion :: nasty str full of poison chars set ^"str= ^^^" ^^^&^^ ^&^"^& %%os%% !random! ^" :: double all quotes ...

Hi Jeb,

Thanks for the explanation, but I think I’ll stick with Dave Benham’s icall macro if I ever find myself in a situation where I’m forced to make extensive use of call set.

Cheers!

Hi Aacini!

I explored a findstr /no solution, but decided it was too messy. There’s no way to tell Unix and Windows line-endings apart, line numbers must be decremented, and what if the last line in the file happens to be the longest?

Cheers!

Hello Again! I returned to this problem after a long break with a fresh perspective. Sure enough, the only practical solution, imho, is a hybrid script: @if (@X==@Y) @then @echo off & setlocal enableextensions disabledelayedexpansion for /f "tokens=1,2" %%A in (' cscript //nologo //e:j...

Hi Jeb, Ah, now I get it! The weird syntax is to guard against the unlikely event that a user has a file called "set.bat" or "set<Space>.bat" on his/her PATH. However did you think to check for that? And one last thing, you said: I reinvent the wheel this year, but this time my n...

Hi Penpen and Jeb! Thanks for the explanations. Just one more pitfall to look out for when writing a Batch file! On a related topic, Jeb wrote in this post : set "safeSet=set^ "" call %%safeSet%% var=123" I was wondering why you didn’t just write: set "safeSet=set" call...

Hi Samir!

Perhaps this post from Nov 2013 may be of interest.

Hello All! Sorry I haven’t posted in a while. My mind has been… elsewhere. Anyways, could someone please explain what’s going on here? @echo off & setlocal enableextensions disabledelayedexpansion set ^"str= hello ^&^"^& world! ^" (call;) call set "str1=%%str%%" ...

Hello All! Sorry I’m late to the discussion, as usual. But my solution takes advantage of the popping the CALL stack technique Siberia-Man told us about on June 7th: @echo off & setlocal enableextensions disabledelayedexpansion set ^"str=^" ^&^^ ^"^^^&^"^& !^^!^^^...

Hi Guys! Sorry for the delay in replying. Here’s what I (eventually) came up with: @echo off & setlocal enableextensions disabledelayedexpansion (call;) set "crlf=%tmp%\crlf.tmp" >"%crlf%" echo( for %%A in ("%crlf%") do set "crlfSize=%%~zA" if %crlfSize% n...

Hello All!

Fascinating topic. But could someone show me how to use this new technique to stop a for /l loop in its tracks?

TIA!

Hi Ed, Thanks for the explanation. Still can’t quite wrap my head around Aacini’s code, though. Will keep trying. In the meantime, I’ve rekindled my obsession with finding the best way to trim leading and trailing whitespace from a string: @echo off & setlocal enableextensions disabledelayedexpa...

Hi Jeb, I was afraid you’d say something like that. But it’s even worse than I originally thought. If the program is executed from the command line using cmd like so: cmd /c prog.cmd "quoted ^ carets" unquoted ^^^^ carets The carets must be escaped a second time for the command line cmd. S...

Hello All! I want to make sure a script I’m writing runs in ANSI mode. The usual procedure is to check for a command line switch and call the script again if not present. The relevant line is: cmd /d /a /c call "%~dpnx0" /ansi %* Trouble is, when I run it with echo on, I notice that unquot...

Hi Antonio, Your last example was amazing. Too bad I can’t understand it! Anyways, I was wondering if it’s possible to change the value of the original string from inside the loop caused by the string split operation… because if it is, we could append to the string what was just taken off, the strin...
