Env-format

Instructions

Create a script env-format.sh, which will print the environment variables that have the following formats:

  • Print the PWD value.
  • All the environment variables that have a letter H in the name, without printing the value of those variables.
$ printenv
SHELL=/bin/bash
QT_ACCESSIBILITY=1
NVM_RC_VERSION=
COLORTERM=truecolor
HOMEBREW_PREFIX=/home/linuxbrew/.linuxbrew
DESKTOP_SESSION=i3
...
PWD=/home/user
LOGNAME=user
MANPATH=/home/linuxbrew/.linuxbrew/share/man:
XDG_SESSION_DESKTOP=i3
XAUTHORITY=/run/user/1000/gdm/Xauthority
WINDOWPATH=2
SHELL=/bin/bash
SSH_AGENT_PID=2900
HOME=/home/user
HOMEBREW_SHELLENV_PREFIX=/home/linuxbrew/.linuxbrew
