There are very few basic Eshell commands -- so-called builtins.
They are: echo, umask, and version.
;_* echo
The echo command repeats its arguments to the screen. It is
optional whether this is done in a Lisp-friendly fashion (so that
the value of echo is useful to a Lisp command using the result of
echo as an argument), or whether it should try to act like a normal
shell echo, and always result in a flat string being returned.
An example of the difference is the following:
echo Hello world
If eshell-plain-echo-behavior is non-nil, this will yield the
string "Hello world". If Lisp behavior is enabled, however, it
will yield a list whose two elements are the strings "Hello" and
"world". The way to write an equivalent expression for both would
be:
echo "Hello world"
This always returns a single string.
;_* umask
The umask command changes the default file permissions for newly created files. It uses the same syntax as bash.
