Compressing files generally makes files smaller and saves space. During the
compression process, the original file is not removed until the compressed file
is complete. This means you will need extra space in the directory to compress
files, and if you have gone over your quota, you will not be able to compress
your files. To get around this problem, you may want to move
(mv command) the file you want to compress to one of the
"scratch" spaces or to /tmp, then compress the
file.
Note: In many cases, Gzip will do a better
job than compress.
- To compress a single file named data1, use
compress data1 or gzip data1.
- To compress all files in a directory that have the string
data in their name, use compress *data* or
gzip *data*.
- To compress all files in a sub-directory named old_data,
use find ./old_data -type f -exec compress {} \; or
find ./old_data -type f -exec gzip {} \;.
