Hi,

a solition might be ci/co, standard on HP-ux and Sun (and maybe more). It's a horrible apllication but it keeps you from these problems.

Of course you can write a script that does, the folowing ? :

#!/usr/local/bin/perl
# Script that creates lock-file

$file=$ARGV[0];
@last_f=split(/\//, $file );
@last_f=reverse @last_f;
$last_f = $last_f[0];

if ( -f "/tmp/${last_f}" ) {
print "Sorry, $last_f is still opened by someone else \n";
}
else {
`touch /tmp/${last_f}`;
$cmd = sprintf("/usr/bin/vi %s",$file);
$status = system($cmd);
`rm /tmp/$last_f`;
}

LEARN ABOUT SUNOS

whereis

whereis(1B)					     SunOS/BSD Compatibility Package Commands					       whereis(1B)

NAME

       whereis - locate the binary, source, and manual page files for a command

SYNOPSIS

       /usr/ucb/whereis [-bmsu] [ -BMS directory...  -f] filename...

DESCRIPTION

       The  whereis utility locates source/binary and manuals sections for specified files. The supplied names are first stripped of leading path-
       name components and any (single) trailing extension of the form .ext, for example, .c.  Prefixes of s. resulting from use  of  source  code
       control are also dealt with. whereis then attempts to locate the desired program in a list of standard places:

       etc
       /sbin
       /usr/bin
       /usr/ccs/bin
       /usr/ccs/lib
       /usr/lang
       /usr/lbin
       /usr/lib
       /usr/sbin
       /usr/ucb
       /usr/ucblib
       /usr/ucbinclude
       /usr/games
       /usr/local
       /usr/local/bin
       /usr/new
       /usr/old
       /usr/hosts
       /usr/include
       /usr/etc

OPTIONS

       The following options are supported:

       -b	Searches only for binaries.

       -B	Changes or otherwise limits the places where whereis searches for binaries.

       -f	Terminates the last directory list and signals the start of file names, and must be used when any of the -B, -M, or -S options are
		used.

       -m	Searches only for manual sections.

       -M	Changes or otherwise limits the places where whereis searches for manual sections.

       -s	Searches only for sources.

       -S	Changes or otherwise limit the places where whereis searches for sources.

       -u	Searches for unusual entries. A file is said to be  unusual  if  it  does  not	have  one  entry  of  each  requested  type.  Thus
		`whereis  -m  -u  *' asks for those files in the current directory which have no documentation.

EXAMPLES

       Example 1: Finding files

       Find all files in /usr/bin which are not documented in /usr/share/man/man1 with source in /usr/src/cmd:

       example% cd /usr/ucb
       example% whereis -u -M /usr/share/man/man1 -S /usr/src/cmd -f *

FILES

       /usr/src/*

       /usr/{doc,man}/*

       /etc, /usr/{lib,bin,ucb,old,new,local}

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWscpu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       chdir(2), attributes(5)

BUGS

       Since whereis uses chdir(2) to run faster, pathnames given with the -M, -S, or -B must be full; that is, they must begin with a `/'.
