tdelete -- Delete a table.
This task deletes tables. The input may be a general filename template, including wildcard characters, or the name of a list file (preceded by the "@" character) containing table names.
The task checks that the file to be deleted really is a table before deleting it. In order to protect against accidental deletion of files other than tables, text tables may be deleted using tdelete only if verify = yes.
- table [file name template]
- A list of one or more tables to be deleted.
- (verify = no) [boolean]
- Prompt for confirmation before deleting? It is possible to delete text tables using tdelete if verify is set to "yes".
- (default_action = yes) [boolean]
- Default action for the verify query. If default_action = yes, then the prompt will come back with "yes?" and striking return will proceed with the delete.
- go_ahead = yes [boolean]
- This is a copy of default_action used for prompting if verify = yes. This parameter is set by the task, it copies the value of default_action, but cannot be directly set by the user.
1. Delete a single table.
cl> tdelete table
2. Delete several tables.
cl> tdelete table1,table2,tab67 cl> tdelete *.tab,a,b,cIn the latter case, the extension is given explicitly because there may be other files beginning with "tab" that are not tables.
3. Delete a list of tables using verify.
cl> tdelete fits*.tab ver+ cl> delete table `fits1.tab' ? (yes): yes cl> delete table `fits2.tab' ? (yes): yes cl> delete table `fits3.tab' ? (yes): yes
Text tables cannot be deleted by tdelete unless verify is set to yes.
