Full Discussion: Want to box the output
Top Forums Shell Programming and Scripting Want to box the output Post 302859175 by in2nix4life on Wednesday 2nd of October 2013 01:43:21 PM
Old 10-02-2013
I wrote a shells script that takes the output from stdin and surrounds it with #s.

Hope this helps.

Code:
#!/bin/bash
#
#

# read from stdin and dump to a temporary file
TMPFILE="/tmp/${0##*/}.$$"
while read -r INPUT
do
    echo $INPUT >> $TMPFILE
done

# get the length of the longest line
END=$(cat $TMPFILE | awk '{if(length($0)>l) l=length($0);}END{print l}')

# add 1 to our end length
LASTCHAR=$(expr $END + 1)

# create header and footer
FHLENGTH=$(expr $LASTCHAR + 5)
HEADER=$(seq -s "#" "$FHLENGTH" | sed 's/[0-9]//g')
FOOTER=$(seq -s "#" "$FHLENGTH" | sed 's/[0-9]//g')

# make the output pretty
echo $HEADER
while read OUTPUT
do
    printf "%1s %-${LASTCHAR}s %1s\n" "#" "$OUTPUT" "#"
done < $TMPFILE
echo $FOOTER

# done
rm -f $TMPFILE
exit 0

Run like so:

./script1 | ./makePretty.sh

glutbuttonboxfunc

glutButtonBoxFunc(3GLUT)					       GLUT						  glutButtonBoxFunc(3GLUT)

NAME

       glutButtonBoxFunc - sets the dial & button box button callback for the current window.

SYNTAX

       void glutButtonBoxFunc(void (*func)(int button, int state));

ARGUMENTS

       func	 The new button box callback function.

DESCRIPTION

       glutButtonBoxFunc  sets the dial & button box button callback for the current window. The dial & button box button callback for a window is
       called when the window has dial & button box input focus (normally, when the mouse is in the window) and the user generates dial  &  button
       box button presses. The button parameter will be the button number (starting at one). The number of available dial & button box buttons can
       be determined with glutDeviceGet(GLUT_NUM_BUTTON_BOX_BUTTONS). The state is either GLUT_UP or GLUT_DOWN indicating whether the callback was
       due to a release or press respectively.

       Registering  a  dial & button box button callback when a dial & button box device is not available is ineffectual and not an error. In this
       case, no dial & button box button callbacks will be generated.

       Passing NULL to glutButtonBoxFunc disables the generation of dial & button box button callbacks. When a new window is created,  no  dial  &
       button box button callback is initially registered.
