Bash script for splitting a filename, extension and path from fullpath

Call the function split_filenames with the first argument as the full filename with path. Alternately, set the variable fullfile to this value.

#!/bin/bash


split_filenames() {

# echo "Called with Arg: $1"

if [ ! "$1" = "" ]

then

fullfile=$1


fi

# echo I got this filename for processing $fullfile

filename=$(basename "$fullfile")

fname=$(basename "$fullfile")

nameonly=${filename%.*}

ext=${fname##*.}


echo "filename $filename"


filename=${fullfile%.*}

pathonly=${fullfile%/*}


if [ "$pathonly" = "$fullfile" ]

then

pathonly="$pat"

fi


echo "Path $pathonly"

echo "Name $nameonly"


chkper=$(echo $fullfile | grep -c "\.")

# echo "Number of periods:$chkper"


if [ ! "$chkper" = "0" ]

then

echo "Extension $ext"

else

echo "No extension"

fi


#out_file=$pathonly/$nameonly"_signed."$ext


}


for i in ~/Dropbox/SSH\ Keys/*

do

echo

echo Path and Name: $i

split_filenames "$i"

#cp "$i" testssh/

done[/code]

In the example, the main event calls the function from a loop which cycles through all the files in the specified directory.

Working with Multiple Windows on Emacs

Split a window into two horizontally: [Ctrl-X] [3]
Split a window into two vertically: [Ctrl-X] [2]
Switch to [O]ther Window : [Ctrl-X] [O] Oh, not zero

Delete current window (remove split) : Ctrl-X 0 This is Ctrl+X and a Zero

My custom emacs file:
Options added are custom color, removed the split window on start.

(add-to-list 'load-path "/path/to/color-theme.el/file")

(require 'color-theme)

(eval-after-load "color-theme"

  '(progn

     (color-theme-initialize)

     (color-theme-clarity)))

(custom-set-variables

  ;; custom-set-variables was added by Custom.

  ;; If you edit it by hand, you could mess it up, so be careful.

  ;; Your init file should contain only one such instance.

  ;; If there is more than one, they won't work right.

 '(inhibit-startup-screen t))

(custom-set-faces

  ;; custom-set-faces was added by Custom.

  ;; If you edit it by hand, you could mess it up, so be careful.

  ;; Your init file should contain only one such instance.

  ;; If there is more than one, they won't work right.

 '(default ((t (:inherit nil :stipple nil :background "black" :foreground "white" :inverse-video nil :box nil :strike-through nil :overline nil :underline nil :slant normal :weight normal :height 140 :width normal :foundry "unknown" :family "Droid Sans Mono")))))

Remove startup split screen in Emacs

Edit your ~/.emacs file to add the following at the end:

;; open with single window
(setq inhibit-startup-screen t)
(add-hook 'emacs-startup-hook 'delete-other-windows)

Note: If ~/.emacs doesnt exist, just create it and paste the above code in it. On restarting Emacs, you’ll notice that the split window has disappeared.
