read
a line of input from the user and store as a user defined typed variable (deprecated)
A readline function to allow a line of data inputted from the terminal and then store that as a typed variable.
This builtin is now deprecated. Please use
read --datatype ...
instead
tread data-type "prompt" var_name
<stdin> -> tread data-type var_name
tread qs "Please paste a URL: " url
out "The query string values included were:"
$url -> format json
out Please paste a URL: -> tread qs url
out "The query string values included were:"
$url -> format json
If tread
is called as a method then the prompt string is
taken from stdin. Otherwise the prompt string will be the first
parameter. However if no prompt string is given then tread
will not write a prompt.
The last parameter will be the variable name to store the string read
by tread
. This variable cannot be prefixed by dollar,
$
, otherwise the shell will write the output of that
variable as the last parameter rather than the name of the variable.
