eshell-convert-numeric-arguments

eshell-convert-numeric-arguments is a variable defined in `esh-util.el'.
Its value is
t


Documentation:
If non-nil, converting arguments of numeric form to Lisp numbers.
Numeric form is tested using the regular expression
`eshell-number-regexp'.

NOTE: If you find that numeric conversions are interfering with the
specification of filenames (for example, in calling `find-file', or
some other Lisp function that deals with files, not numbers), add the
following in your init file:

(put 'find-file 'eshell-no-numeric-conversions t)

Any function with the property `eshell-no-numeric-conversions' set to
a non-nil value, will be passed strings, not numbers, even when an
argument matches `eshell-number-regexp'.

You can customize this variable.
