suppose a perl script attempts to run an application with an argument of file
using "system" function, it fails when both folder names have spaces.
[code]
@REM='
@echo off
perl -wS %~nx0 %*
goto :eof
';
system(@ARGV);
[\code]
e.g. only [3] fails
[1] FOO.bat notepad.exe "\"C:\Program Files\FreeAmp\ReadMe.txt\""
[2] FOO.bat "\"C:\Program Files\Windows NT\Accessories\wordpad.exe\"" C:\WINNT\setup.log
[3] FOO.bat "\"C:\Program Files\Windows NT\Accessories\wordpad.exe\"" "\"C:\Program Files\FreeAmp\ReadMe.txt\""

WHY?

all cases work outside of perl.
I would appreciate if you come up with a workaround
that beats MS idio(t)syncracy in space-contaminated folders.

oops. I goofed in [code] bracketing.
the perl script FOO.bat should read:
コード:

@REM=' 

@echo off 

perl -wS %~nx0 %* 

goto :eof 

'; 

system(@ARGV);


and the samples runs should look like this:
コード:

[1] FOO.bat notepad.exe "\"C:\Program Files\FreeAmp\ReadMe.txt\"" 

[2] FOO.bat "\"C:\Program Files\Windows NT\Accessories\wordpad.exe\"" C:\WINNT\setuplog.txt

[3] FOO.bat "\"C:\Program Files\Windows NT\Accessories\wordpad.exe\"" "\"C:\Program Files\FreeAmp\ReadMe.txt\""


thanks

hmmm... the [code] quoting is still not cooperative.

in the sample runs, all double-double quotes ("") should read ("\").
yes, a double quote (") followed by an escape (\) and another double quote (").
I swear.

my humble apologies.

the easiest way I found so far is:
to use "cmd/b" as the first arg of perl's system() as below

コード:

FOO.bat "cmd/b" "\"C:\Program Files\Windows NT\Accessories\wordpad.exe\"" "\"C:\Program Files\FreeAmp\ReadMe.txt\""


I wonder this space-sensitivity in the first arg is a bug or feature?

sorry, I goofed again.

should be "start/b" in place of "cmd/b"
引用:

FOO "start/b" "\"C:\Program Files\Windows NT\Accessories\wordpad.exe\"" "\"
C:\Program Files\FreeAmp\ReadMe.txt\""


(my 'back-slash' char would be your 'YEN' sign)
