Question Question on storing a variable from a rename action.
I have a simple if statement I am working with to validate if a file exist and rename it using the following method:
Code:
if [ -a ".htaccess" ];then mv .htaccess .htaccess.bak_$(date +%F-%T);fi;

The output is just as it should be and I need to have that saved as a variable so that I can implement a revert changes option calling a $var that would equate to the .htaccess.bak_2015-05-04-18:49:13 generated and renaming it back. I realize I could easily make a command that reverts the changes finding the file using regular expressions although that seems dodgy as even if the likelihood of encountering a file named similarly is low it is possible.

My understanding of storing and calling variables is still pretty basic and I gladly welcome any help for a solution and understanding of a save in this manner.

p.s also counts as intro thread. Hello!

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
