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)

exit 0

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:

imager::color::float
Imager::Color::Float(3pm) User Contributed Perl Documentation Imager::Color::Float(3pm)NAME
Imager::Color::Float - Rough floating point sample color handling
SYNOPSIS
$color = Imager::Color->new($red, $green, $blue);
$color = Imager::Color->new($red, $green, $blue, $alpha);
$color = Imager::Color->new("#C0C0FF"); # html color specification
$color->set($red, $green, $blue);
$color->set($red, $green, $blue, $alpha);
$color->set("#C0C0FF"); # html color specification
($red, $green, $blue, $alpha) = $color->rgba();
@hsv = $color->hsv(); # not implemented but proposed
$color->info();
DESCRIPTION
This module handles creating color objects used by Imager. The idea is that in the future this module will be able to handle color space
calculations as well.
A floating point Imager color consists of up to four components, each in the range 0.0 to 1.0. Unfortunately the meaning of the components
can change depending on the type of image you're dealing with:
o for 3 or 4 channel images the color components are red, green, blue, alpha.
o for 1 or 2 channel images the color components are gray, alpha, with the other two components ignored.
An alpha value of zero is fully transparent, an alpha value of 1.0 is fully opaque.
METHODS
new This creates a color object to pass to functions that need a color argument.
set This changes an already defined color. Note that this does not affect any places where the color has been used previously.
rgba()
This returns the red, green, blue and alpha channels of the color the object contains.
info
Calling info merely dumps the relevant color to the log.
