Top Forums Shell Programming and Scripting Sequential numbering from 1 to ten Post 302890158 by Chubler_XL on Tuesday 25th of February 2014 12:07:30 PM
Old 02-25-2014
This version shuffles the existing files down and places new file at #1 (deleting old #10).

Code:
#!/bin/bash

mv_down() {
   rm -f 10_*
   for ((i=9; i ; i--)) {
       printf -v FILE "%s" ${i}_*
       [ -f "$FILE" ] || continue
       BASE=${FILE#${i}_}
       mv -f "$FILE" "$((i+1))_$BASE"
   }
   mv "$1" "1_$1"
}

cd folder
while true
do
    for file in *
    do
       [[ ! -f "$file" || "$file" = [1-9]_* || "$file" = 10_* ]] && continue
       mv_down "$file"
    done
    sleep 1
done

m17n-dump

m17n-dump(1)							 The m17n Library						      m17n-dump(1)

NAME

       m17n-dump - dump text image

SYNOPSIS

       m17n-dump [ OPTION ... ] [ FILE ]

DESCRIPTION

       Dump a text as PNG image file.

       The PNG file is written to a file created in the current directory with the name 'BASE.png' where BASE is the basename of FILE. If FILE is
       omitted, text is read from standard input, and the image is dumped into the file 'output.png'.

       The following OPTIONs are available.

       o -s SIZE

       SIZE is the font size in point. The default font size is 12 point.

       o -d DPI

       DPI is the resolution in dots per inch. The default resolution is 300 dpi.

       o -p PAPER

       PAPER is the paper size: a4, a4r, a5, a5r, b5, b5r, letter, WxH, or W. In the case of WxH, W and H are the width and height in millimeter.
       In the case of W, W is the width in millimeter. If this option is specified, PAPER limits the image size. If FILE is too large for a single
       page, multiple files with the names 'BASE.01.png', 'BASE.02.png', etc. are created.

       o -m MARGIN

       MARGIN is the horizontal and vertical margin in millimeter. The default margin is 20 mm. It is ignored when PAPER is not specified.

       o -c POS

       POS is the character position of cursor to draw. By default, cursor is not drawn.

       o -x

       FILE is assumed to be an XML file generated by the serialize facility of the m17n library, and FILE is deserialized before an image is
       created.

       o -w

       Each line is broken at word boundary.

       o -f FILTER

       FILTER is a string containing a shell command line. If this option is specified, the PNG image is not written info a file but is given to
       FILTER as standard input. If FILTER contains '%s', that part is replaced by a basename of FILE. So, the default behaviour is the same as
       specifying 'cat >
	   %s.png' as FILTER.

       If FILTER is just '-', the PNG image is written to stdout.

       o -a

       Enable anti-alias drawing.

       o --family FAMILY

       Prefer a font whose family name is FAMILY.

       o --language LANG

       Prefer a font specified for the language LANG. LANG must be a 2-letter code of ISO 630 (e.g. 'en' for English).

       o -fg FOREGROUND

       Specify the text color. The supported color names are those of HTML 4.0 and '#RRGGBB' notation.

       o -bg BACKGROUND

       Specify the background color. The supported color names are the same as FOREGROUND, except that if 'transparent' is specified, make the
       background transparent.

       o -r

       Specify that the orientation of the text is right-to-left.

       o -q

       Quiet mode. Don't print any messages.

       o --version

       Print the version number.

       o -h, --help

       Print this message.
