Top Forums Shell Programming and Scripting Bash directory loop and order by creation date? Post 302987803 by Don Cragun on Friday 16th of December 2016 06:25:27 AM

If you want to ignore everything you've been told and do not want to print directory names in order of date of creation and instead want to print directory names in order of increasing file status change times, you can use:
Code:
ls -1cd /home/test/*/

(note that the 1st option in the above command is the digit 1; not the lowercase letter l). Using the -1 option tells ls to produce names one per line without needing to feed the output through a while read echo loop.

If your directories are located on a filesystem type that does save creation times in addition to file status change times, on some systems you could get a list of directories in increasing order of creation times with:
Code:
ls -1Ud /home/test/*/

but since standard filesystems don't have a creation time (only a status change time as drl mentioned), the option letter to print the creation time (if there is one) may be different on your system. Search the ls man page on your system for an option containing the word creation to see if there is an option to sort output by creation time on your system, and if there is, what option character invokes it and what filesystem types have that information.

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME
libbash -- A bash shared libraries package. DESCRIPTION
libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may want to load and use in scripts of your own. It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries. Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1). A bash shared library that can be loaded using ldbash(1) must answer 4 requirments: 1. It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash). 2. It must contain a line that begins with '#EXPORT='. That line will contain (after the '=') a list of functions that the library exports. I.e. all the function that will be usable after loading that library will be listed in that line. 3. It must contain a line that begins with '#REQUIRE='. That line will contain (after the '=') a list of bash libraries that are required for our library. I.e. every bash library that is in use in our bash library must be listed there. 4. The library must be listed (For more information, see ldbashconfig(8)). Basic guidelines for writing library of your own: 1. Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions. 2. Try to declare all variables intended for internal use as local. 3. Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with: __<library_name>_ For example, internal function myfoosort of hashstash library should be named as __hashstash_myfoosort This helps to avoid conflicts in global name space when using libraries that come from different vendors. 4. See html manual for full version of this guide. AUTHORS
