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:
