If you specify the same directory in your FPATH and PATH
variables, and you type in a "command" (e.g. hello), and
there exists a file called hello in that common directory,
will the shell first attempt to interpret this file as a
function, and failing this, then re-attempt to interpret
it as a script/binary-executable?
I've always kept my FPATH and PATH pathnames separate, but
my current work location is mixing the two (i.e. they put
scripts, binaries AND functions in the "bin" directory).
I have a bin directory for scripts and binaries, and a
funcs directory for functions.
Thanks!

Hi,
I have a file with about 60 lines of path:
app-defaults/boxXYZ.......
I want to change this to /my/path/goes/here/app-defaults/boxXYZ, but of course vi doesn't like the regualr :s/old/new/ command.
Is there any other quick way to do this?
Thanks ;) (2 Replies)

Here is how i begin scripts:

whereis
WHEREIS(1) General Commands Manual WHEREIS(1)
NAME
whereis - locate the binary, source, and manual page files for a command
SYNOPSIS
whereis [ -bmsu ] [ -BMS directory... -f ] filename ...
DESCRIPTION
whereis locates source/binary and manuals sections for specified files. The supplied names are first stripped of leading pathname compo-
nents 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 Linux places.
OPTIONS
-b Search only for binaries.
-m Search only for manual sections.
-s Search only for sources.
-u Search 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.
-B Change or otherwise limit the places where whereis searches for binaries.
-M Change or otherwise limit the places where whereis searches for manual sections.
-S Change or otherwise limit the places where whereis searches for sources.
-f Terminate 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.
EXAMPLE
Find all files in /usr/bin which are not documented in /usr/man/man1 with source in /usr/src:
example% cd /usr/bin
example% whereis -u -M /usr/man/man1 -S /usr/src -f *
FILES
/{bin,sbin,etc}
/usr/{lib,bin,old,new,local,games,include,etc,src,man,sbin,
X386,TeX,g++-include}
/usr/local/{X386,TeX,X11,include,lib,man,etc,bin,games,emacs}
SEE ALSO
chdir(2V)
BUGS
Since whereis uses chdir(2V) to run faster, pathnames given with the -M, -S, or -B must be full; that is, they must begin with a `/'.
whereis has a hard-coded path, so may not always find what you're looking for.
