Good day
I am fairly new to Shell Scripting.
I want a script to check if a process is up by checking the process's PID and then return a value for when it's running which would be 0. If it isn't running it should give any other value that 0.
Any Help is appreciated

xmstringbytecompare
XmStringByteCompare(library call) XmStringByteCompare(library call)
NAME
XmStringByteCompare -- A compound string function that indicates the results of a byte-by-byte comparison
SYNOPSIS
#include <Xm/Xm.h>
Boolean XmStringByteCompare(
XmString s1,
XmString s2);
DESCRIPTION
This function is obsolete and exists for compatibility with previous releases. 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 com-
pound 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.
s1 Specifies a compound string to be compared with s2
s2 Specifies a compound string to be compared with s1
RETURN
Returns True if two compound strings are identical byte-by-byte.
