bash PS1 256 colors with bold

bash terminal colors prompt

Solution 1

You can write it as any of those:

echo -e "\e[1;38;05;${code}m $code: Test"
echo -e "\e[1m\e[38;05;${code}m $code: Test";
echo -e "\e[38;05;${code}m\e[1m $code: Test";
echo -e "\e[38;05;${code};1m $code: Test";
tput bold; tput setaf "$code" # provided the terminfo database is
                              # properly populated

You can run tput bold only once provided you don't reset the boldness with a tput sgr0 or \e[m or \e[0m.

Solution 2

To supplement Stephane's example, here's a quick shell function to list all 256 colors:

#!/bin/bash
esc=$'\033'
for row in {0..15} ; 
do
    rowtext=
    for col in {0..15}; 
    do
        color=$(( $row * 16 + $col))
        BG="${esc}[48;5;${color}m"
        rowtext=${rowtext}$BG\ 
        if [[ $color -lt 100 ]]; then rowtext=${rowtext}$BG\   ;fi 
        if [[ $color -lt 10 ]]; then rowtext=${rowtext}$BG\   ;fi 
        rowtext=${rowtext}$BG${color}
        rowtext=${rowtext}$BG\ 
    done
    echo "${rowtext}${esc}[00m "
done

This is a quick "port" of a zsh function I have to bash. I seems to work (in bash), or at least well enough.

The color code number is displayed in the color block. This is what you'd use in your prompt or elsewhere to set the color.

I have a table named People in the following format:

Date | Name.

When I count the people by Grouping By Name with
```
Select Date, Name, count(*)
From People
Group By Date, Name;
```
Will give the following
```
Date        Name        count(*)
10          Peter       25
10          John        30
10          Mark        25
11          Peter       15
11          John        10
11          Mark        5
```
But I would like the following result:
```
Date    Peter   John    Mark
10      25      30      25
11      15      10      5
```
Is this possible? This is a simple example of a more complicated database. If someone helps me in solving this problem I will use the concept to implement it in my table

Thanks!

  What SQL product are you using (hint: search for pivot and whatever RDBMS you're using, and you should find the answer)?

  Hi, which RDBMS do you use? If you use MS-SQL try to use the PIVOT- Statement.

  Further to @Damian's comment - I would seatch for your RDBMS platform with search terms pivot and crosstab and you should find out if this is possible or not...

  This is usually known as a Pivot (table). Depending on your RDBMS there may be non-standard functions to do this, else you'll find yourself hard-coding each Name in CASE statements. Reporting tools are better at handling this sort of output.

  Duplicate of column value in a single row and likely many others.

  Add 1; in it: \e[1;38;05;${code}m. Better to use tput setaf "$code"; tput bold.

  @StephaneChazelas Wow I didn't know I could add another code inside sequence. I was certain whet there could be max three parts. For example: \e[38;05;44m or \e[1;31m. Does the order of codes between semicolons matter? Your answer is correct. Please write reply and I will accept it. Thx.

Some escape characters seems to get lost during the copy-paste.

An escape character at the beginning of BG got lost. You should use escape sequences instead to avoid this kind of mishap. You can't use $BG[0] in bash, you have to write it ${BG:0:1} (for an array it would be ${array[0]}).
