For Loop sequence question
I am using a for loop in a shell. My question is how does it list out the files in the example below. Does it list the files by name? How can I list the files by date so it will list the oldest file first in the sequence.
Thanks!
for f in /dir/*.*
echo $f
end

whereis
whereis(1) General Commands Manual whereis(1)
Name
whereis - locate source, binary, and or manual for program
Syntax
whereis [-sbm] [-u] [-SBM dir... -f] name...
Description
The command locates source/binary and manuals sections for specified files. The supplied names are first stripped of leading pathname com-
ponents 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. The command then attempts to locate the desired program in a list of standard places.
Options
-S dir
Search for source files in specified directory.
-B dir
Search for binary files in given directory.
-M dir
Search for manual section files in given directory.
-b Searches only for binary files.
-f Terminates last directory list created from use of -S, -B or -M flags and signals the start of file names.
-m Searches only for manual section files.
-s Searches only for source files.
-u Searches for files that do not have one of binary, source or manual section files. 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
The following finds all the files in which are not documented in with source in
cd /usr/ucb
whereis -u -M /usr/man/man1 -S /usr/src/cmd -f *
Restrictions
Since the program uses to run faster, pathnames given with the -M -S and -B must be full. That is, they must begin with a ``/''.
Files
/usr/src/*
/usr/{doc,man}/*
/lib, /etc, /usr/{lib,bin,ucb,old,new,local}
