Re: How to add environment variable value to hardstatus line

[Neal Fultz]

I do something similar, I use the following in my screenrc to set the title to current dir:

 setenv PROMPT_COMMAND 'echo -ne "\033_`pwd`\033\\"'

Then you can use %t in the status bar or wherever.

Hi Mario

you can output escape sequence string to virtual terminal,
so as to display any messages you like in hardstatus line.

bash has some convenient features PROMPT_COMMAND or PS1
to execute any commands before displaying shell prompt message.

for example to display $(envname) in hardstatus line
[[.bashrc]]
# send message to screen hardstatus %h
if [[ "$TERM" =~ "screen" ]]; then
  PROMPT_COMMAND='echo -ne "\033k\033\0134\033k$(envname)\033\\"'
endif
