#Linux check kernel version manual
dumpversion has been available for decades but note that it may only give the major version number.įrom info gcc dumpversion in the manual from gcc-12.2.0: Note that -dumpfullversion was added in gcc 7.1.0. (we need to check that $version is non-empty as otherwise is-at-least would compare zsh's own version). Version=$(gcc -dumpfullversion 2> /dev/null) &
Zsh also comes with an autoloadable is-at-least function aimed for that (intended to compare zsh version numbers but can be used with any version provided they use similar versioning scheme as zsh's): #! /bin/zsh. 1.012 sorts the same as 1.12 but since one has to come before the other and we do an equality comparison we'll end up considering it not at_least 1.12. Note that 1.12-pre1 or 1.12-alpha3 would be considered greater than 1.12. The output above shows that the Linux kernel is 64-bit and its version is 4.15.0-54, where: 4 - Kernel Version. With zsh, you can use it's numeric ordering ( Ordering in reverse) parameter expansion flags: at_least() ]Īnd then: if at_least $version 1.12 then To find out what version of the Linux kernel is running on your system, type the following command: uname -srm.
