comment How to put a box around something in GIMP?
I'd border the selection and just fill it in a new layer.

comment What is the Ubuntu equivalent of OSX `chmod -h` flag?
Incidentally POSIX does specify the fchmodat function, which can be used to change the mode of symbolic links (optional feature - systems that do not support it, including Linux, return error EOPNOTSUPP), but nothing in the chmod command to use this. Only -R is defined in POSIX.

are you sure ssh cares about the permissions on the symbolic link and not the permissions on /somewhere/else/privatekey?

The ability to set permissions on symlinks is not specified in even the latest version, it's a BSD extension.

comment How to delete all files except one named file from a specific folder
What shell does this work on? Does it work on ubuntu's default bash? EDIT: nevermind, found the info, proposed an edit.

comment Why does bash thinks that 010 is 8?
@Tim if so I couldn't figure out how. ${${N%?}:-0} works in zsh but not in bash or ksh. (Also, :- in my comment above should have been :-0}

@Tim to do that you can use ${N%?} to chop the last digit and then ${N:-} to replace blank with 0.

comment Where are commands `fg`, `bg` and `jobs` installed?
@user136104 The reason why something like echo or kill can exist as both commands and builtins and most of the other builtins aren't is because they cannot function without being part of the shell. What exactly would an external bg do? It doesn't know what process to continue, and it can't control its interaction with the terminal.

comment How to use grep output as a path for cd?
No, it's not guaranteed, in theory a shell could use a named fifo or temp file, though there's no reason to.

Of course, if you want to get technical, the shell uses a pipe internally to read the command output.

comment bash: /home/…/program: cannot execute binary file
@BartoszOlszewski "AMD-64" refers to the architecture used on modern 64-bit processors made by both Intel and AMD, because it was used by AMD first (Intel had a rival 64-bit architecture called Itanium).

comment In which directories can “nobody” user write?
@muru IIRC this means anyone can create files in the directory, and can open files that they know exist, but cannot list the contents.

comment In which directories can “nobody” user write?
shouldn't this be -perm -002? That way you aren't checking everyone to have every permission, just world-write permission
