gunzip unknown suffix -- ignored


hi, i have about 100 gzipped files that are named like vendor-837-12-04-20-14:44:37.253.

i am trying to gunzip all of them but i keep getting errors like:
gunzip: vendor-837-12-04-20-14:44:37.253: unknown suffix -- ignored

when i 'cp vendor-837-12-04-20-14:44:37.253 vendor-837-12-04-20-14:44:37.253.gz; gunzip vendor-837-12-04-20-14:44:37.253.gz' it behaves correctly but i'll get a hand-cramp from doing that more than 100 times.

since unix uses the magic number to know the file-type, isnt the filename irrelevant ?

thanks,

Hello

My advise is to escape the - and the : characters, so your instruction end like:

Code:
gunzip [OPTIONS] vendor\-837\-12\-04\-20\-14\:44\:37\.253
Other whise the CLI try to interprate the metacharacters

Regards

^ thanks for the advice but i am having the same problem like so:
gunzip: vendor.837: unknown suffix -- ignored

but gunzip vendor.837.gz works perfectly.

how to make it so gunzip will take any filename (seems kinda' windows-like to expect an extension on every filename) ?

try to use
zcat

zcat will uncompress
files that have the correct magic number whether they have a
.gz suffix or not.
Kind regards

ok, sorry now i get the problem

look in the man of your gunzip for the -S option, if it exist try the command:

Code:
gunzip -S "" vendor-837-12-04-20-14:44:37.253

thanks, getting even closer, i am now getting this error
gunzip: vendor-837-12-04-20-14:44:37.253: cannot decompress onto itself

seems like some limitation of gunzip that i will need to handle in some sort of for loop.

thanks alot.


edit: i got creative and hacked something together that worx:
Code:
zgrep -E "(.|^$)" vendor-837-12-04-20-14:44:37.253 > vendor-837-12-04-20-14:44:37.253.txt
also, i just discovered the obvious:
Code:
cat vendor-837-12-04-20-14:44:37.253 | gunzip > vendor-837-12-04-20-14:44:37.253.txt
