Top Forums Shell Programming and Scripting How to compare a parameter to a string Post 302385743 by shira on Saturday 9th of January 2010 01:14:41 PM

ok, I discovered the problem, but it's very odd.
At the beginning of the script I defined parameter.
I echoed it right after the definition and it was okay.

I echoed it right before the if like you said, but it showed me that inside parameter, instead of string, there was 0!

It's as if parameter was changed throughout the script, but I didn't touch it until I got to the if part!

Do you have any idea why this thing could happen?

Thanks.

XmStringByteCompare(3X) 												   XmStringByteCompare(3X)

NAME
XmStringByteCompare - A compound string function that indicates the results of a byte-by-byte comparison SYNOPSIS
#include <Xm/Xm.h> Boolean XmStringByteCompare (s1, s2) XmString s1; XmString s2; DESCRIPTION
XmStringByteCompare returns a Boolean indicating the results of a byte-by-byte comparison of two compound strings. In general, if two compound strings are created with the same (char *) string using XmStringCreateLocalized in the same language environ- ment, the compound strings compare as equal. If two compound strings are created with the same (char *) string and the same font list ele- ment tag set other than XmFONTLIST_DEFAULT_TAG using XmStringCreate, the strings compare as equal. In some cases, once a compound string is put into a widget, that string is converted into an internal form to allow faster processing. Part of the conversion process strips out unnecessary or redundant information. If an application then does an XtGetValues to retrieve a compound string from a widget (specifically, Label and all of its subclasses), it is not guaranteed that the compound string returned is byte-for-byte the same as the string given to the widget originally. Specifies a compound string to be compared with s2 Specifies a com- pound string to be compared with s1 RETURN VALUE
Returns True if two compound strings are identical byte-by-byte. SEE ALSO
