Full Discussion: Bash and Awk for creating directories and moving files
Top Forums Shell Programming and Scripting Bash and Awk for creating directories and moving files Post 302218263 by chihung on Thursday 24th of July 2008 09:23:16 PM

We do not have to test for individual directory level 'cos if the bottom directory exists, the parent level should exist. Also, mkdir -p will make all the non-existing parent directories. Also, I introduce 'short circurt' && to ensure directory exist before I move the file.

We can also avoid all the repeating code using in extracting yy/mm/dd/hh by using 'set --' and sed. sed will change 2 digits with 2 digits + space so that it can put the result back to "set --" to set the positional variables accordingly

This is my contribution, it should work (even on sh)
Code:
for i in *.jpg
do
   # yy is $1, mm is $2, dd is $3, hh is $4
   set -- `echo $i | sed -e 's/\([0-9][0-9]\)/\1 /g'`
   dir="$1/$2/$3/$4"
   [ ! -d $dir ] && mkdir -p $dir && mv $i $dir
done

__________________________________________________________________________________________________________________________________________________

NAME

       tk_chooseDirectory - pops up a dialog box for the user to select a directory.

SYNOPSIS

       tk_chooseDirectory ?option value ...?
_________________________________________________________________

DESCRIPTION

       The  procedure tk_chooseDirectory pops up a dialog box for the user to select a directory. The following option-value pairs are possible as
       command line arguments:

       -initialdir dirname
	      Specifies that the directories in directory should be displayed when the dialog pops up. If this parameter is  not  specified,  then
	      the  directories	in  the current working directory are displayed. If the parameter specifies a relative path, the return value will
	      convert the relative path to an absolute path.

       -mustexist boolean
	      Specifies whether the user may specify non-existent directories.	If this parameter is true, then the user may only select  directo-
	      ries that already exist.	The default value is false.

       -parent window
	      Makes window the logical parent of the dialog. The dialog is displayed on top of its parent window. On Mac OS X, this turns the file
	      dialog into a sheet attached to the parent window.

       -title titleString
	      Specifies a string to display as the title of the dialog box. If this option is not specified, then a default  title  will  be  dis-
	      played.

EXAMPLE

	      set dir [tk_chooseDirectory 
		      -initialdir ~ -title "Choose a directory"]
	      if {$dir eq ""} {
		 label .l -text "No directory selected"
	      } else {
		 label .l -text "Selected $dir"
	      }
