LainTrainOld XKCD, still relevant
š“ššštar --version
WhoLooksHereOr is it -v
Depends. Short options are probably safer if the particular version and flavor of tar are unknown.
0x4E4FSo you either het version or verboseā¦slick AF š.
-v is verbose
atx_aquarianI hitched my horse to just what I consider the basicsāzip and unzipāand that has made it easy for me. But Iāve been stuck on those.
Extract anything:
tar xf <archive_file>Create a tbz2 archive:
tar cjf <archive_file.tbz2> <stuff to put in it>(And tossing in a -v is pretty universal, if thatās your thing.)
Some day, instead of commenting on a reddit Lemmy post, I think Iāll Google how to tell it to use .xz.
Ok, you know what? Today is finally that day. Itās just capital -J instead of lower-case -j! Thatās easy enough to remember, I guess.
Stay by the phone always. We may need you to defuse a bomb someday.
Never thought Iād learn how to use
tar on a meme post.
Memes are one of the best source for Linux info š.
boredsquirrel (he)I guess
man tar is cheating, but it is a command involving tar. Not a command using tar, but a tar commandā¦
I suppose
tar --help would technically be a valid invoking of the binary itself if man tar doesn't
But it would not work on older non-GNU versions of tar.
GNU introduced the āāfooā style long options, and it was a long time before Unix versions began adopting them.
It didnāt say you could only enter one try, just that you had 10 seconds. The man page should give you something
True. But then I would use
curl cheat.sh/tar
I just can recall
tar xvzf but can't even remember what it's supposed to do.
eXtract, Verbose, gZip, File.
Not sure why it doesnāt need the dash though.
r4venwI always learnt it as Xtract Zee File and to make a tar ball, you want to Compress Zee File
The dash used to be how to could tell how long someone had been using tar. If they started with Linux, they probably use a dash. If they started on a UNIX variant, they probably donāt. Either way, the dash isnāt needed.
Also recently learned that recent versions of tar will autodetect compression. So for extraction, you just need ātar xf ā
Sacrilege.
tar doesnāt need dashes because itās weird.
eyatar cJf file.tar.xz /path/to/file
tar xJf file.tar.xz /path/to/file.tar.xz -C /path/to/untar
is not very hard to remember
Unless you use it daily, I think thatās something Iād struggle with memorising, Iād just alias it tbh along with ls options
tar -czvf tar_name.tar.gz ./
Yep, have this one committed to memory. Though if it asked me to uncompress a tarball, then Iād be fucked
tar xcvf this_awesome_file.tgz
hallettjI think you want to remove the
c because that means ācreateā an archive, and youāre missing a z which applies gzip decompression/compression
I suppose it is tar version dependent, but on any recent Linux version I have used, you can just tar xvf <tar_name.tar.{z,gz,xz,etc}> and it will automatically figure out if it is compressed, what tools were used to compress it, and how to decompress it.
But you are right, x and c are mutually exclusive.
Yeap, apparently I canāt type. So, weād all be dead anyway with that bomb.
File not found, now we are dead.
Sounds like an error message from a
valid tar command
v_krishnaI even read this aloud in my head as āCREATE ZE VUCKING FILEā in a particularly bad German accent same as over 20 years ago when a friend I worked for drilled it in my head.
Read it in tf2 medics voice
EdgarallenpwnI didnāt realize that was my default German voice in my head. Thx
lol thatās honestly a great mnemonic
tsonfeirAnyone else make an untar.sh?
Magistertar, the tape archiver, I used it with tape, early 90s
FuglyDuckSudo halt -fn
beanSomehow, idk why. This one is stuck in my head:
tar -zxvf filename.tar.gztar xzvf
eXtract Ze Vucking File
I have to do this command often at work and I can never remember the letters perfectly. This is actually useful, thanks!
Same, never used a mnemonic for it or anything, just
zxvf
Like itās any other word
z=zip (default in most tar(, x=eXtract, v=verbose (not needed in most cases), f=target
verbose ā¦ not needed?
If the words donāt happen how can I trust computer magic?
Yeah, how do I know that the PC isnāt slacking?
Monitor the room temperature.
The bomb runs AIX. Iām sorry, youāre dead
tar zxvf filename.tar.gz file?
Nope,
tar doesnāt handle compression on AIX. So it would be something like gzip -cd filename.tar.gz | tar xvf -
linearchaosIāve never had a problem remembering tar, but properly using PV, somehow Iām just not able to store that information in my brain.
Do people not use tab complete?
Found the person whoās never used tar :-P
Zos_KiaThereās an easy mnemonic for that : Compress Ze Vucking File !
SynapseAlways think about tar commands in your best German accent !
JackGreenEarth
woelkchenJust
tar, no arguments. Does nothing, still a valid command, no?
Exit code 2 -> boom
rrconkletar: You must specify one of the '-Acdtrux', '--delete' or '--test-label' options
Try 'tar --help' or 'tar --usage' for more information.
