Terminal: Difference between revisions

Latest revision as of 14:25, 28 February 2018

The linux terminal is your lifeblood. There are so many - TOO MANY - options. I'll gather a few of my favorite things here.

Host-specific color and banner

This is mucho importante to quickly tell which machine you are on:

use figlet and jp2a to create ascii art
update ~/.bashrc to echo the ascii art in a host-specific color, and to persist that color in the prompt
make sure to include an interactive check to avoid the banner if not interactive

See the many examples of .bashrc in the config repo.

Monitor running processes

top, htop are meh
This must be perfected, it is the answer, it shows a TREE of terminal processes:

watch -n 1 ps fT

Drop a dead ssh session

Remember this one to drop a dead ssh session!

-HOW DID I LIVE SO LONG WITHOUT THIS!
+* top, htop are meh
-You can do keyboard-driven copy-paste from terminal buffer using screen!
+* This must be perfected, it is the answer, it shows a TREE of terminal processes:
-* Ctrl-A-esc to get into buffer navigation mode
+  watch -n 1 ps fT
-* space to mark the start of the copy buffer (non-column)
-* space to mark the end of the copy buffer
-* then you can use Ctrl-A-] to paste - wait, wut?  useless... what about X buffer?
-** add this to "your screen .rc file" to send buffer to X clipboard too!
- bindkey -m ' ' eval 'stuff \040' 'writebuf' 'exec sh -c "/usr/bin/pbcopy < /tmp/screen-exchange"'
-=== Always use screen when ssh'ing ===
-Best to accomplish this with a script.
-This will also allow us to provide host-specific background graphics and profile colors, sweeeeet!
-    mah-haus-provided ssh commands!
-        mh bitpost {screenname}
-            save term background/profile
-            change term background/profile - with host pic in upper right!!
-            use this script to ssh bitpost:

-                also:
-                    On my Ubuntu system (10.4) I had to modify the regular expression to account for the date/time info it prints next to each session.
-                    if(/^\s*(\d+)\.(\S+)\s+(([^)]*))\s+(([^)‌]*))/) { ($num, $tag, $status) = ($1, $2, $4); –
-                or:
-                    ssh -t user@some.domain.com /usr/bin/screen -xRR
-                    -t is needed to force terminal creation (even tho sending a command)
-                    -x
-                    -R restore existing or create if none
-                    # see MY screen settings with at to see what i really want
-                better to let screen do the ssh?
-                   screen -S 1-9 -p 0 -X screen -t Remote ssh 19
-            reset term background/profile
