function::set_int_arg - Linux
Overview
function::set_int_arg
is a Linux command used to set the value of an integer argument for a function invocation. It allows you to dynamically assign values to function arguments during program execution.
Syntax
function::set_int_arg <function_name> <arg_index> <value>
Parameters:
<function_name>
: Name of the function to set the argument for.<arg_index>
: 0-based index of the argument to set.<value>
: Integer value to assign to the argument.
Options/Flags
None
Examples
Example 1:
Set the second argument of the my_function
function to 10.
function::set_int_arg my_function 1 10
Example 2:
Set the first argument of the calculate_average
function to 1000.
function::set_int_arg calculate_average 0 1000
Common Issues
- Argument index out of bounds: Ensure that the provided
<arg_index>
is within the valid range for the function’s arguments. - Invalid value type: The
<value>
must be an integer. Attempting to set a non-integer value will result in an error.
Integration
function::set_int_arg
can be combined with other Linux commands to dynamically modify function arguments at runtime.
Example:
Use function::set_int_arg
and sort
to sort a list of integers based on the second element of each tuple.
sort -k2,2n < input_file | function::set_int_arg my_sort_function 1
