Bash script: problem with a function which use colors
Hello guys
I've a some issue with a function which use the bash colors in my script.
An example :
Code:
#!/bin/bash
set -x
log_in(){
host="srv1"
remote_files="log/"
LOG_FILE="logfile"
green='\033[0;32m'
red='\033[0;31m'
none='\033[0m'
if [[ $1 = "red" ]]; then
color_in_red=("${red}"$2"${none}")
echo -e "$color_in_red"
echo -e "$(date)" "$2" >> "${LOG_FILE}"
elif [[ $1 = "green" ]]; then
color_in_green=("${green}"$2"${none}")
echo -e "$(date)" "$2" >> "${LOG_FILE}"
echo -e "$color_in_green"
fi
}
log_in red ""$host" The read right is missing on \""$remote_files"\""
The problem is it write good in the logfile but in output it stop write from the first variable, I should be more clear with the output that I had :
Code:
rsync_user@vmtest1:/home/scripts/test$ ./test.sh
+ host=srv1
+ remote_files=log/
+ LOG_FILE=logfile
+ log_in green 'srv1 The read right is missing on "log/"'
+ green='\033[0;32m'
+ red='\033[0;31m'
+ none='\033[0m'
+ [[ green = \r\e\d ]]
+ [[ green = \g\r\e\e\n ]]
+ color_in_green=("${green}"$2"${none}")
++ date
+ echo -e 'Wed Jan 18 17:33:16 CET 2017' 'srv1 The read right is missing on "log/"'
+ echo -e '\033[0;32msrv1'
srv1
rsync_user@vmtest1:/home/scripts/test$
And in the logfile, it works :
Code:
rsync_user@vmtest1:/home/scripts/test$ cat logfile
Wed Jan 18 17:33:16 CET 2017 srv1 The read right is missing on "log/"
Then, all in my console become red or green.. until I type "ll" maybe another commands..
I was trying to see all combinations of foreground and background colors in BASH.
This works fine for me,
echo -e '\E[37;46m TEXT'
but when I tried the below script, the variables i and j do not expand.
#!/bin/sh
for i in `seq 30 37` # foreground
do
for j in `seq 40... (4 Replies)

I am trying to figure out why I am having a "problem" with some functions in a bash script I am running. The reason for air quoting is that the functions are working, they are just not displaying anything to screen when called from another function. Here's an example:

ppmquantall
ppmquantall(1) General Commands Manual ppmquantall(1)NAME
ppmquantall - run ppmquant on a bunch of files all at once, so they share a common colormap
SYNOPSIS
ppmquantall [-ext extension] ncolors ppmfile ...
DESCRIPTION
Takes a bunch of portable pixmap as input. Chooses ncolors colors to best represent all of the images, maps the existing colors to the new
ones, and overwrites the input files with the new quantized versions.
If you don't want to overwrite your input files, use the -ext option. The output files are then named the same as the input files, plus a
period and the extension text you specify.
Verbose explanation: Let's say you've got a dozen pixmaps that you want to display on the screen all at the same time. Your screen can
only display 256 different colors, but the pixmaps have a total of a thousand or so different colors. For a single pixmap you solve this
problem with ppmquant; this script solves it for multiple pixmaps. All it does is concatenate them together into one big pixmap, run
ppmquant on that, and then split it up into little pixmaps again.
(Note that another way to solve this problem is to pre-select a set of colors and then use ppmquant's -map option to separately quantize
each pixmap to that set.)

It's a csh script. Csh scripts are not portable to System V. Scripts in general are not portable to non-Unix environments.
