Those that have never had a hard drive fail. That's useful for testing but portage will not remember those settings, so they will be reverted later.įor the paranoid, there is a special USE flag that turns off all USE flags set before it. Repeated uses of this flag will cause ripgrep to disable more and more of its filtering. Together, this defines your global USE settnig.įurther down still are your per package USE settings defined in /etc/portage/eįor completeness, You may set USE=. definitions whose name is write : rg fn write( src/printer.rs. The next layer are your additions and subtractions in nf USE flags are set in an hierarchical manner.Īt the top level are the USE flags that come with your profile. “And even in authoritarian countries, information networks are helping people discover new facts and making governments more accountable.”– Hillary Clinton, Jan. But if you don't like them, you can either switch to a profile that suits you better, or override them with nf or /etc/portage/e. Flags set by the profile or the ebuild are usually good defaults. You can't change these as they would be overwritten next time you do emerge -sync. grep searches the named input FILEs (or standard input if no files are named, or if a single hyphen-minus () is given as file name) for lines containing a. Note: The grep command with the -F flag is the same. Default flags can be defined by the profile (for example, profiles/targets/desktop/gnome/e), or by an ebuild itself (it would have IUSE="+flag" in it). Treats each specified pattern as a string instead of a regular expression. is a regular expression operator that matches any character). would be the equivalent of: grep textfile. The flags you set in nf are meant to override the default flags. See the -F (fixed string, as opposed to regular expression) and -x (exact: match the whole line) options. Thx Is there any config file for profile USE flgas? Add the -x option if those fixed strings have to make up the entire matched line (as opposed to be found anywhere within the line without it). The 'binary file' detection is codepage-sensitive if grep expects UTF-8 input as usual on Linux, it will actually end up detecting 'ANSI' (Windows-125x, ISO 8859-x) encoded text files as binary files. I assume it's done this way to make it easier to choose your 'base' system from which you can refine up or down without cluttering your nf that much. Or use -F and pass the strings one per line or with several -e s: grep -Fe string1 -e string2 -e string3. Use grep -a to force a file to always be treated as text. USE flags in your nf work as an addition on top of your profile USE flags. My question is How can it be possible that 2 ways of checking out flags output different results? I suppose those are the flags set when choosing the profile during installation. I've just installed Gentoo for the first time.ĭuring installation I chose "desktop/gnome (stable)" profile but after finally rebooting when I check out /etc/portage/nf I only see one flag which I never got to used static-libs.īut if emerge -info | grep ^USE a lot of other flags are shown. Posted: Fri 10:48 pm Post subject: emerge -info | grep ^USE outputs too many USE flags Gentoo Forums Forum Index Installing Gentoo emerge -info | grep ^USE outputs too many USE flags Inverse of previous command: displays a count of the lines in myfile.txt which do not contain the word 'hope'. The forked processes/connections handle key exchange, encryption, authentication, command execution, and data exchange. It forks a new process for each incoming connection.

You'll also learn the differences between these tools - for example, awk doesn't support backreferences within regexp definition (i.e. This post covers Basic Regular Expressions (BRE) and Extended Regular Expressions (ERE) syntax supported by GNU grep, sed and awk.
