Garbage Command [GAR]
Finds and recovers wasted space in the current workfile.
GARBAGE
(Q = no summary)
If you keep adding lines to a workfile and editing them, eventually you will get an "Error: Full" message in Line mode or "File nearly full!" in Visual mode, and be unable to add more lines. One method of continuing at this point is to use the Garbage command.
/garbage
/gar {minimal command name}Garbage combines partially full blocks to squeeze out free blocks, but it also searches the workfile for any blocks that have been "lost" (i.e., are no longer on the "free list" or the "text list"). It does not make your file any smaller, it just allows you to continue editing by finding usable space within the file.
Garbage prints a summary of how much space it recovered and how much is available in the file. The summary report can be suppressed using GarbageQ.
5 blocks squeezed out, 2 found, 55 used,
10 on free list, 9 for expansion.In this example, Garbage reports that 5 blocks were retrieved via squeezing, 2 lost blocks were found, 55 blocks are currently used to hold text, 10 empty blocks are held on a "deleted-block" list (the free list), and 9 blocks are available if the EOF is expanded toward the LIMIT.
