V_UNIXWHICH Search system path for an executable program [F]=(C,E)
Inputs: C name of file to search for (excluding extension)
E list of extensions [default = '.com;.exe;.bat' unless C contains '.']
Outputs: F Full pathname of executable (use FILEPARTS() to split up)
Notes: (1) This is WINDOWS specific and needs to be fixed to work on UNIX systems
(2) The search is case insensitive (like most of WINDOWS).
(3) The routine does not cache the directory listings so you
should avoid doing the same search many times if you care
about speed.
(4) To include all files that CMD.EXE will search, set e=v_winenvar('pathext')
(5) As well as their normal full-length name, WINDOWS files and folders have
a short name assigned by the operating system that is 8 characters long
(+ 3 more for the extension). These short names are usually hidden from the
user and UNIXWHICH, unlike the operating system, will not search for them.0001 function f=v_unixwhich(c,e) 0002 %V_UNIXWHICH Search system path for an executable program [F]=(C,E) 0003 % 0004 % Inputs: C name of file to search for (excluding extension) 0005 % E list of extensions [default = '.com;.exe;.bat' unless C contains '.'] 0006 % 0007 % Outputs: F Full pathname of executable (use FILEPARTS() to split up) 0008 % 0009 % Notes: (1) This is WINDOWS specific and needs to be fixed to work on UNIX systems 0010 % (2) The search is case insensitive (like most of WINDOWS). 0011 % (3) The routine does not cache the directory listings so you 0012 % should avoid doing the same search many times if you care 0013 % about speed. 0014 % (4) To include all files that CMD.EXE will search, set e=v_winenvar('pathext') 0015 % (5) As well as their normal full-length name, WINDOWS files and folders have 0016 % a short name assigned by the operating system that is 8 characters long 0017 % (+ 3 more for the extension).
