5 modern alternatives to essential Linux command-line tools
I already use ag as an alternative to grep and di as an alternative to df, but fd was new to me.

It has some weird build dependencies like xsltproc, asciidoc & gettext to build docs & cargo (seems to be built in a mix of c++ & rust).

Then the xmllint check run by a2x fails as it won’t download the DTD, so replace all instances of

$(A2X)

in the Makefile with

$(A2X) –no-xmllint

Wondering *which* version of java is running as a daemon?

ls -l /proc/PID/exe

If you press ‘l’ you’ll see all the files the highlighted process has open (presuming you have permissions).
