I like to be able to do export BROWSER="lynx -cfg=~/.lynx.cfg". I tried this directly, and I also tried setting an alias alias lynx="lynx -cfg=~/.lynx.cfg", but these didn't work. (Meaning that tools that use this variable to launch a browser still ignored my config file or didn't launch the browser at all.)

  • Does it work if you rename your configuration file into ~/.lynxrc and don't use an option? – Kusalananda Nov 23 '18 at 6:48
  • @Kusalananda No, it doesn't work. It seems to be using another default config file. – HappyFace Nov 23 '18 at 9:00
  • How/where did you set the alias?; How did you try to use it? – ctrl-alt-delor Nov 23 '18 at 10:04

$BROWSER is understood by several utilities as being your web browser of choice.

Depending on the utility, it will be expected to contain:

  1. the path or name of the executable
  2. a list of words the first of which is the path or name and the other ones a list of initial arguments. If you're lucky, it will also understand some form of quoting similar to what shells do.
  3. (very unlikely and it would be a very unwise thing to do) the start of a shell command line.

If you were in the first case, I'd expect the utility you tried it in to complain about an unexisting "lynx -cfg=~/.lynx.cfg" command.

In the third case, note that shells don't expand the ~ in -cfg=~/.lynx.cfg. zsh only does it when the magicequalsubst option is enabled. bash only expands a ~ after a = if what's on the left of = looks like a valid variable name and it's not in POSIX mode.

However lynx (at least version 2.8.9dev.16 on my system) does appear to understand ~ as meaning one's home directory by itself, so I'd expect yours to work for utilities in the second and third category.

$ BROWSER='echo -cfg=~' sensible-browser foo
-cfg=~ foo

So either your browser is of a fourth category that ignores anything but the first word or only takes a hint as to what your browser is; or your version of lynx doesn't understand ~ as meaning home.

Run your utility as strace -fe execve the-utility to see what it tries to execute.

In the case of your versions of lynx not treating ~ as home, you can define $BROWSER as:

export BROWSER="lynx -cfg=$HOME/.lynx.cfg"

(assuming $HOME doesn't contain blanks or quotes (or other characters special to a shell))

In any case, you should be able to define $BROWSER as a script that passes the correct parameters to lynx, like:

#! /bin/sh -
exec lynx -cfg="$HOME/.lynx.cfg" "$@"

and use that as your $BROWSER.

Incidentally, if your $HOME started with ~ characters, that would fool lynx, which is why it's not such a good idea for lynx to handle those ~ by itself.

I don't think you can however you could try:

Must use absolute path.

export BROWSER='/home/username/lynx.sh'

Create new file lynx.sh in home dir.

linx -cfg=/home/username/.lynx.cfg

Make it exicutable.


Launching Browser should launch lynx.



whereis lynx

Use in next step.

Edit bash_aliases:

Must use absolute path to: lynx.cfg
Must use absolute path to: lynx, if not in /usr/bin/

alias=lynx='/path/to/lynx -cfg=/home/username/.lynx.cfg'

Must use ' ' if path contains special charactors.

  • I thought of the first solution and was going to post it but you beat me to it :)) I don’t understand the second solution though? How is this different from a normal alias, which I tried and it didn’t work? – HappyFace Nov 23 '18 at 7:06
  • Forgot must use absolute path.. – Michael Prokopec Nov 23 '18 at 7:16
  • The second solution doesn't work on zsh. – HappyFace Nov 23 '18 at 8:48
  • The first solution makes the tool that is using BROWSER hang, though only after adding "$@" to the end of your script. Without this change, the tool just exits after a few seconds. I tried echoing hi in the script, and it was not echoed back to me when I ran the tool. (I am running ddgr --unsafe -n 6 --noprompt '!w apple' if it helps.) – HappyFace Nov 23 '18 at 8:58
