 Posted: Fri Jul 20, 2018 1:02 am Post subject: Trim equery list to only show applications |
 |
|
Is there a way to trim or filter the `equery list' output so that it only lists applications users can run (or normally would run).
For instance listing for '*' shows 703 results, but many of them are for libs, perl-core, coreutils, etc.
Essentially I want to find all the executables/applications my user can run such as axel, wget, socat, netcat, ffmpeg, etc.
Perhaps there is a better method such as parsing /bin and /usr/bin?
Any tips or tricks to find out this information.
Thanks. |

Well, there's some trouble: coreutils does contains files people run, and run often -- should this be included? Kind of ambiguous here.
You can also base it on your world file, what you emerged explicitly: /var/lib/portage/world ...

| To find files in the typical paths that you could run, you could start with find /bin /sbin /usr/bin /usr/sbin -perm -o=x. There are some corner cases that this will get wrong, but it's mostly accurate. What are you trying to do? There are many programs that you can run, but probably never will run directly, if at all. |

Although I agree with Hu's sentiment: | Code: | #!/bin/bash
# Proof of concept. Find all executables on the path.
for dir in `sed -e "s/:/ /g" -e "s|~|${HOME}/|g" <<<${PATH}` ; do
find $dir -maxdepth 1 -type f -executable
done |
Finds the root-executable programs if you run it as root and the user-executable programs if run as a regular user.

The above suggestions will work I guess with a little bit of leg work on my side.
More or less what I was trying to do was create a listing of all commands that are useful but I don't use all the time. For instance the cpulimit application is very useful, but I may not use it for long periods at a time so I may forget that I have it installed.
I'm thinking about organizing them by category, so perhaps basing my work off the world file may be a better option since they are already organized with a category I just have to reorganize the information. |

to strictly answer the question, here's what you "were" looking for
| Code: | | equery f "*" | grep "/bin/\|/sbin/" |
(make sure to quote the "*") |

John ... hold my beer :)
| Code: | % print $0
/bin/zsh
% print -l $^path/*(Nx) |
zsh also offers the 'commands' array:
| Code: | % print ${#${commands[@]}}

best ... khay |
