A cute trick for bash and xterm:
I work with a lot of xterms. For years, I have been using pwd,
cd, and mouse-cut-and-paste to copy the working directory from
one window to another.
Then it's time you met screen.
screen gives you lots of terminal sessions in one window (or on one
virtual console).
yum -y install screen
screen
# then to create another session
^AC
# To list them:
^A"
# To advance to the next:
^A<space>
# To retreat to the previous
^Ap
# to split
^AS
# To switch to the next split
^A<tab>
# To unsplit
^AQ
There are more.
screen's great.
atm I have ten xterms and konsole (konsoles usually have several
sessions), and one screen on a vc with eight sessions, an ssh session
across my LAN with screen and five sessions; when I dial into the
Internet I have another two sshes to remote screens with probably
another half-dozen sessions each. I'm logged into eleven ttys (including
those waiting to ssh to remote hosts). I run X on tty13 (and that's not
counted in any of the others).
screen's great.
Now I have a better way, involving some aliases in .bashrc:
alias sd='pwd > ~/.sd'
alias ds='cd `cat ~/.sd`'
I type 'sd' in the xterm I want to copy the working directory
from, and 'ds' in the xterm that I want to copy the working
directory to.
It is actually secure - the backtick'ed cat feeds directly
to cd, so even if .sd is corrupted somehow, it cannot
execute arbitrary code.
I use 'sd' and 'ds' because I am left handed; 'kl' and 'lk'
might be easier for right handers, and I will humbly accept
the honor of being immortalized in the initials. ;-)
I'm not going to use it, but it _is_ cute:-)
I should add, I routinely "chattr +a .bash_history" and set these:
HISTCONTROL=ignoredups
HISTFILE=/home/summer/.bash_history
HISTFILESIZE=100000
Sometimes I want to expose my recent bash history to a second session.
This saves it:
\ exec -l /bin/bash
Note, "\ exec" means <space>exec - the command has a leading space.
