2015年8月5日 · tar -x -v -f httpd-2.2.31.tar Single character switches can be grouped together eg -xvf and seemingly unique to tar, the first argument will be treated as switches regardless of whether there is a hyphen.

2019年7月21日 · -f option in tar means that the next argument is the name of the target tar file. So after the -f option you can't place another option, for example the following syntax is wrong:

2016年2月5日 · In the case of f(x) = x ** 2 the ** is being performed by numpy on the entire array not on a per element basis. For example if f(x) is 'lambda x: x + x" then the answer is very different because numpy concatenates the arrays instead of doing per element addition. Is this really the intended comparison? Please explain. –

zxf means: gunzip (the 'z' letter) and extract (the 'x' letter) from file (the 'f' letter, and the file name follows). xvf means: extract (the 'x' letter) and be verbose (the 'v' letter) from file (the 'f' letter, and the file name follows). You renamed the openresty-1.9.7.3.tar to openresty-1.9.7.3.tar.gz, but this didn't make it gzipped tar ...

x means --extract. v means --verbose. f means --file. z means --gzip. You can combine one-letter arguments together, and f takes an argument, the filename. There is something you have to watch out for: Short options' letters may be clumped together, but you are not required to do this (as compared to old options; see below).

2014年12月31日 · x extract - extract the files from the archive. v verbose - list all files as they are processed. z uncompress - in this case, or compress if creating a tar. f use a file (The file you are uncompressing)....but there are lots more switches for tar. Take a look.

2021年2月15日 · The answer to this is not something hard and fast and can vary between different companies implementing it. Like for example, changing the MAC address in a VF can be something that a VF cannot do without the PF's access or changing the MTU of the VF, in that case. The VF would ping its corresponding PF via mailbox to request the change.

2016年5月24日 · Today I tried to unzip one file in Linux, I used 2 kinds of orders 1.tar zxvf zookeeper-3.4.6.tar.gz 2.tar -zxvf zookeeper-3.4.6.tar.gz It seems both of the 2 orders are same, do they have some

2014年6月24日 · Assert position at the beginning of the string «^» Match a single character in the range between “a” and “z” «[a-z]{1}» Exactly 1 times «{1}» Match a single character present in the list below «[a-z0-9_]{3,13}» Between 3 and 13 times, as many times as possible, giving back as needed (greedy) «{3,13}» A character in the range between “a” and “z” «a-z» A character in ...

If a virtual member function vf is declared in a class Base and in a class Derived, derived directly or indirectly from Base, a member function vf with the same name, parameter-type-list, cv-qualification, and ref-qualifier (or absence of same) as Base::vf is declared, then Derived::vf is also virtual (whether or not it is so declared) and it ...
