Usually you can check $^O to find out what OS you are running under. Under ActivePerl or Strawberry Perl $^O will return MSWin32 `C:\>perl -e "print $^O, qq{\n};" MSWin32` [download] Under Cygwin perl $^O will return cygwin. `$ perl -e "print $^O, qq{\n};" cygwin` [download] This of course becomes slightly tricky when one runs ActivePerl or Strawberry Perl under the Cygwin environment or Cygwin perl under cmd.exe The Cygwin environment inherits all the environment variables from the Windows environment. But it appears to set several BASH related vars: `BASH=/cygdrive/c/GNUWin32/bin/bash BASH_ARGC=() BASH_ARGV=() BASH_LINENO=() BASH_SOURCE=() BASH_VERSINFO=([0]="3" [1]="2" [2]="39" [3]="20"[4]="release" [5]="i68 +6-pc-cygwin") BASH_VERSION='3.2.39(20)-release'` [download] So to check whether you are running under Cygwin you could use a combination of checking $^O and $ENV{BASH_VERSION} etc.	[reply] [d/l] [select]

See `$OSNAME` or `$^O` in perlvar. Be sure to read the notes for Windows platforms. -- No matter how great and destructive your problems may seem now, remember, you've probably only seen the tip of them. [1]	[reply] [d/l] [select]
