Program: DELETE

Purpose: Delete sets

Category: UTILITY

File: delete.c

Author: M. Vogelaar

Keywords:

** LIST= List with GIPSY set names? Y/[N]

Can be either Y or N. If user specifies LIST=Y, a list
with set names in the current directory is displayed.
The default is LIST=N


INSET= Give name of set to delete: [stop]

Enter:
1) One set name, e.g.:
INSET=AURORA
2) Set names separated by a semicolon (;) e.g.:
INSET=AURORA;ngc3079a;ngc3079b
3) A path followed by a set name (no wildcard expansion):
INSET=./WORK/ngc400
4) Set name(s) containing the wildcard character '*'.
Wildcards can appear everywhere in a name.
The wildcard expansion works only in the current
directory!
INSET=ngc* (Delete all GIPSY sets that start
with 'ngc')
INSET=* (Delete all GIPSY sets in current dir.)

The names of sets which the user wants to delete
are asked in a loop. Press carriage return to abort this
loop and to stop the program.


OK= Ok to delete ? Y/[N]

Confirm the choice for EACH file that you entered
with INSET=
Long file names are cut off. A number of dots indicate
if this has happened.



Description: DELETE deletes GIPSY sets (image part and descriptor
part). After the introduction of the GDS server,
it became more important to be able to delete sets
within the environment where the server is running.
If f.i. you delete sets with the unix 'rm' command,
the program DISK will still list those sets if the
server is still running. Program DELETE doe the job
properly. It checks whether a file is a valid GIPSY set
and will warn you if it is not (program will display
the corresponding GDS error like: GDS -- bad descriptor
header). However, you still can delete these invalid sets.
The program stores the names of all files that end
on '.descr'. This list is necessary if you want to
use a wildcard expansion using the asterisk character
'*'. This explains why wildcard expansion can only
be used in the current directory. If a set (entered
with INSET=) does not exist, then a warning is displayed
in your log area. If a set exists, but does not conform
to the rules for a valid GIPSY set, then a warning
is displayed in the log area together with the
corresponding GDS error, and a warning will be inserted
in the OK= prompt. Notice that it is still possible
to delete such files. So program DELETE can delete
your very important backupless text file 'important.descr'
if that is what you want.
