Practical and interesting bash command prompt line

Practical and interesting bash command prompt line

 

The color and so on can be used freely.

1. Add a smiley face symbol to the successfully executed command:

 

If the command is successfully executed, you will receive a smiling face as your command line prompt. Once the command fails, the command line prompt will be replaced with a crying face. Flash and highlight.

 

PS1 = "\ 'If [\ $? = 0]; Then ECHO \ [\ e [40 \; 33 \; 5 \; 1m \] ^ _ ^ \ [\ e [0m \]; else echo \ [\ e [40 \; 31 \; 5 \; 1m \] @ [email protected] \ [\ e [0m \]; FI \ '[\ [email protected] \ H: \ W] \ $" Echo 'export PS1 = "\ 'If [\ $? = 0]; Then ECHO \ [\ e [40 \; 33 \; 5 \; 1m \] ^ _ ^ \ [\ e [0m \]; else echo \ [\ e [40 \; 31 \; 5 \; 1m \] @ [email protected] \ [\ e [0m \]; FI \ '[\ [email protected] \ H: \ W] \ $ "'>/etc/bashrc ./Etc/bashrc

 

 

 

2.Change the color of the failed command

 

I personally like this.

 

The color of the command line prompt will change after your last command fails to run, and the long path of the command will shorten the space for entering the command, this command prompt also contains the command numbers of each history bash command to facilitate re-extraction and running.

 

PS1 = "\ [\ 033 [40; 33; 1m \] [\!] \ 'If [[\ $? = "0"]; then Echo "\ [\ 033 [32m \]"; else echo "\ [\ 033 [31m \]"; FI \ '[\ [email protected] \ H: \ 'If [['pwd | WC-c | tr-d ""'> 18]; then ECHO "\ W"; else echo "\ W"; FI \ '] \ $ \ [\ 033 [0m \] "; echo-ne "\ 033] 0; 'hostname-s': 'pwd' \ 007" Echo 'export PS1 = "\ [\ 033 [40; 33; 1m \] [\!] \ 'If [[\ $? = "0"]; then Echo "\ [\ 033 [32m \]"; else echo "\ [\ 033 [31m \]"; FI \ '[\ [email protected] \ H: \ 'If [['pwd | WC-c | tr-d ""'> 18]; then ECHO "\ W"; else echo "\ W"; FI \ '] \ $ \ [\ 033 [0m \] "; echo-ne "\ 033] 0; 'hostname-s': 'pwd' \ 007" '>/etc/bashrc ./Etc/bashrc

 

 

3. multiline prompt:

 

PS1 = "\ n \ [\ 033 [35m \] \ $ (/bin/date) \ n \ [\ 033 [32m \] \ W \ n \ [\ 033 [1; 31m \] \ [email protected] \ H: \ [\ 033 [1; 34m \] \ $ (/usr/bin/tty |/bin/sed-E's #/dev/# '): \ [\ 033 [1; 36m \] \ $(/bin/LS-1 |/usr/bin/WC-L |/bin/SED's ### G ') files \ [\ 033 [1; 33m \] \ $ (/bin/LS-lah |/bin/grep-M 1 Total |/bin/SED's/total //') B \ [\ 033 [0m \]-> \ [\ 033 [0m \]" Echo 'ps1 = "\ n \ [\ 033 [35m \] \ $ (/bin/date) \ n \ [\ 033 [32m \] \ W \ n \ [\ 033 [1; 31m \] \ [email protected] \ H: \ [\ 033 [1; 34m \] \ $ (/usr/bin/tty |/bin/sed-E's #/dev/# '): \ [\ 033 [1; 36m \] \ $(/bin/LS-1 |/usr/bin/WC-L |/bin/SED's ### G ') files \ [\ 033 [1; 33m \] \ $ (/bin/LS-lah |/bin/grep-M 1 Total |/bin/SED's/total //') B \ [\ 033 [0m \]-> \ [\ 033 [0m \] "'>/etc/bashrc ./Etc/bashrc

 

 

 

 

4. multi-color prompt:

 

 

PS1 = "\ [\ 033 [40; 33; 1m \] \ t \ [\ 033 [M \]-\ [\ 033 [40; 36; 1 m \] \ U \ [\ 033 [M \] @ \ [\ 033 [40; 32; 1 m \] \ H: \ [\ 033 [33; 1 m \] \ W \ [\ 033 [M \] \ $" Echo 'ps1 = "\ [\ 033 [40; 33; 1m \] \ t \ [\ 033 [M \]-\ [\ 033 [40; 36; 1 m \] \ U \ [\ 033 [M \] @ \ [\ 033 [40; 32; 1 m \] \ H: \ [\ 033 [33; 1 m \] \ W \ [\ 033 [M \] \ $ "'>/etc/bashrc ./Etc/bashrc

 

 

 

5. display the complete path:

 

2 rows at the minimum (plus the empty rows at the top ). In the first line, you can get a full path information, and in the second line, you can get a user name. If you are uncomfortable with the empty lines in each command prompt line, you just need to remove the first \ n and it will be OK.

 

PS1 = "[\ [\ 033 [40; 32; 1m \] \ W] \ [\ 033 [0m \] \ n \ [\ 033 [1; 36m \] \ U \ [\ 033 [1; 33m \]-> \ [\ 033 [0m \]" Echo 'ps1 = "[\ [\ 033 [40; 32; 1m \] \ W] \ [\ 033 [0m \] \ n \ [\ 033 [1; 36m \] \ U \ [\ 033 [1; 33m \]-> \ [\ 033 [0m \] "'>/etc/bashrc ./Etc/bashrc

 

 

6. display the number of running tasks in the background:

 

PS1 = "\ [\ 033 [40; 32; 1m \] \ [email protected] \ H: \ [\ e [M \] \ [\ e [1; 37m \] \ W \ [\ e [M \] \ n \ [\ e [1; 33m \] hist :\! \ [\ E [0; 33m \] \ [\ e [1; 31m \] jobs: \ J \ $ \ [\ e [M \]" Echo 'ps1 = "\ [\ 033 [40; 32; 1m \] \ [email protected] \ H: \ [\ e [M \] \ [\ e [1; 37m \] \ W \ [\ e [M \] \ n \ [\ e [1; 33m \] hist :\! \ [\ E [0; 33m \] \ [\ e [1; 31m \] jobs: \ J \ $ \ [\ e [M \] "'>/etc/bashrc ./Etc/bashrc

 

 

7. Display path information:

 

PS1 = "\ n \ [\ e [30; 1m \] \ [\ 016 \] l \ [\ 017 \] (\ [\ e [34; 1 m \] \ [email protected] \ H \ [\ e [30; 1 m \])-(\ [\ e [34; 1 m \] \ J \ [\ e [30; 1 m \])-(\ [\ e [34; 1 m \] \ @ \ D \ [\ e [30; 1 MB \])-> \ [\ e [30; 1 m \] \ n \ [\ 016 \] m \ [\ 017 \]-(\ [\ [\ e [32; 1 m \] \ W \ [\ e [30; 1 m \])-(\ [\ e [32; 1 m \] \ $(/bin/LS-1 |/usr/bin/WC-L |/bin/SED's: G') files, \ $ (/bin/LS-lah |/bin/grep-M 1 Total |/bin/SED's/total // ') B \ [\ e [30; 1 MB \])-> \ [\ e [0m \]"

 

 

 

 

8.

 

PS1 = "\ n \ [\ e [32; 1m \] (\ [\ e [37; 1m \] \ U \ [\ e [32; 1m \]) -(\ [\ e [37; 1m \] jobs: \ J \ [\ e [32; 1m \])-(\ [\ e [37; 1 m \] \ W \ [\ e [32; 1 m \]) \ n (\ [\ e [37; 1 m \]! \! \ [\ E [32; 1m \])-> \ [\ e [0m \]"

 

 

 

 

9.

 

PS1 = "\ [\ e [1; 34m \] \ U \ [\ e [M \] \ [\ e [1; 31m \] @ \ [\ e [M \] \ [\ e [1; 33m \] \ H \ [\ e [M \] \ [\ e [1; 34m \]: \ [\ e [M \] \ [\ e [1; 32m \] \ W \ [\ e [M \] \ [\ e [1; 32m \] \ n (\ [\ e [37; 1m \]! \! \ [\ E [32; 1m \]) \ [\ e [M \] \ [\ e [1; 35m \] $ \ [\ e [M \]"
