question about cygpath

brownie_cookie · 05-30-2011, 09:04 AM

Hi all

I'm working with a plugin I've downloaded from the Nagios exchange website.
Now in this plugin there is some kind of command (?) being used, like CYGPATH...
but can someone explain what it does?

here is the code that is being used:

Code:

# OS specific support (must be 'true' or 'false').
cygwin=false;
case "`uname`" in
    CYGWIN*)
        cygwin=true
        ;;
esac

# For Cygwin, ensure paths are in UNIX format before anything is touched
if $cygwin ; then
    [ -n "$JBOSS_HOME" ] &&
        JBOSS_HOME=`cygpath --unix "$JBOSS_HOME"`
    [ -n "$JAVA_HOME" ] &&
        JAVA_HOME=`cygpath --unix "$JAVA_HOME"`
fi

Can someone help me with this and explain what's happening here?
Thanks in advance

the cygwin environment makes a Windows installation feel Unix-like, e.g. you can open a terminal and run familiar commands, such as ls, cd, cat, vi, and ssh:

Code:

berhanie@latptop ~$ uname
CYGWIN_NT-6.1

the plugin's code tests whether it is running inside a cygwin environment rather than on a real Unix-like system, and, if so, converts certain paths from a possibly Windows format into Unix:

Code:

berhanie@latptop ~$ echo $COMSPEC
C:\Windows\system32\cmd.exe

berhanie@latptop ~$ cygpath --unix $COMSPEC
/cygdrive/c/Windows/system32/cmd.exe

okay thanks!
but i'm using a Linux OS through a local terminal (PuTTy), so i don't need him to check it's running on a Windows platform...
how can i manage that?

there's no reason to change anything. it just makes
things more general: the same script works on both Linux
and Cygwin.
