Hello all, I have a bash function that opens Safari (I'm on OS X) with a specified argument.
Here it is :
Code:
function safari
{
#Safari bash function
TLDS=( "http://www." ".com" ".org" ".net" ".gov" ".edu" )
if [ $1 = "-o" ]; then
open -a Safari ${TLDS[0]}$2${TLDS[2]}
elif [ $1 = "-n" ]; then
open -a Safari ${TLDS[0]}$2${TLDS[3]}
elif [ $1 = "-g" ]; then
open -a Safari ${TLDS[0]}$2${TLDS[4]}
elif [ $1 = "-e" ]; then
open -a Safari ${TLDS[0]}$2${TLDS[5]}
elif [ $1 = "-c" ]; then
open -a Safari ${TLDS[0]}$2${TLDS[1]}
else
open -a Safari ${TLDS[0]}$1${TLDS[1]}
fi
}
I don't have a problem with the function, but I would like to know if my function can have a command history, like after each argument is taken, is it possible that i could write it to a file for later retrieval?
Does anyone know of a way to mimic the up arrow/down arrow type bash behavior within a shell script?
Say I have a scripted menu, and would like to be able to up arrow to bring up the last X number of lines of user input?
Thanks to anybody with a suggestion. :) (0 Replies)

Moderators,
Please excuse if I am in the wrong section.
I have a question that someone may know the answer to. We know that a current bash shell keeps a record of all commands in a buffer. When the shell is terminated this buffer is written out to ~/.bash_history for the user.
I know... (2 Replies)
Hi,
I want to export bash history to a file, I used the following command

Thanks a lot.... (2 Replies)

I am trying to create my custom prompt and I have almost succeeded. Right now I have PS1='\n\\$\ '
What I have not figured out is how to make the directories bold when I'm using commands ls or ls -la.
Any idea how to do it???
Many thanx. (2 Replies)

How can I create a history function? (By "read" command or so)

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
