Scanning file backwards
Is there any way to look for a directory path that is listed any number of lines *before* a keyword in an error message?
I have a script that is trying to process different files that are always down a certain portion of a path, and if there is an error, then says there is an error, contact "the vendor". The count of lines between the path/file that's listed and the actual error is always different, so I can't "cut" based on that pattern. Here's basically what it looks like in the log:
\\server\dir\dir\appdir\...\filename
varied number of lines of data
Unknown problem: "Contact the vendor"
Is there any way to look for the keyword "vendor" and scan "backwards" to find the path/file which I can then cut, put into another file, and manipulate further?
Thanks for any help you can provide,

get_filename
get_filename(3alleg4) Allegro manual get_filename(3alleg4)
NAME
get_filename - Returns a pointer to the filename portion of a path. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
char *get_filename(const char *path);
DESCRIPTION
Finds out the filename portion of a completely specified file path. Both `' and `/' are recognized as directory separators under DOS and
Windows. However, only `/' is recognized as directory separator under other platforms. Example:
get_executable_name(name, sizeof(name));
allegro_message("Running `%s'
", get_filename(name));
Note that Allegro won't perform any IO operations during the verification. This means that if you have `/a/path/like/this/', which doesn't
have a filename, the function will return a pointer to the trailing null character. However, if you have `/a/path/like/this', Allegro will
return a pointer to `this', even if it is a valid directory.
RETURN VALUE
Returns a pointer to the portion of `path' where the filename starts, or the beginning of `path' if no valid filename is found (eg. you are
processing a path with backslashes under Unix).
