The /hdel command deletes an item/data-value pair from an existing hash table.
Synopsis
/hdel [-sw] <table> <item>
Switches
- -s - Displays the Deletion action if the variable exists, displays error if table doesn't exist, no display if the table exists but the item does not.
- -w - Treats <table> as a wildcard and deletes all matching tables.
Parameters
- <table> - The table which contains the item you are deleting
- <item> - the item-name associated with a value to delete. Can be a wildcard when using -w switch.
Example
alias hdel_example { ;add items hadd -m example academic a hadd example academy a hadd example accelerate a hadd example accelerator a hadd example accept a hadd example access a hadd example accident a hadd example because b ;number of items echo -a $hget(example, 0).item ;remove everything by one hdel -w example a* ;number of items echo -a $hget(example, 0).item ;free table hfree example }
//hfree -sw test | hadd -m1 test item1 | hadd test item* | echo -a 1st item is $hget(test,1).item | hdel -w test item* | echo -a there are $hget(test,0).item items remaining * Demonstrates that an item can be created and deleted containing an asterisk. If the -w switch is deleted, only 1 of the 2 items is deleted because of an exact item-name match with "item*". //hfree -sw test | hmake -s test | hdel -s test itemname | echo -a message 1 | hfree -s test | hdel -s test itemname | echo -a message 2 * Demonstrates that deleting a non-existent item from an existing table allows the script flow to continue, but deleting an item from a non-existent table is an error halting the script flow preventing the 2nd message from displaying.
