It prints myvideo.srt subtitle files in myvideo.avi, saving it in myvideo_subtitled.avi
I didn't come up with this myself, but I always add this to my .bash_aliases file. It's essentially the same idea as running "sudo !!" except it's much easier to type. (You can't just alias "sudo !!", it doesn't really work for reasons I don't understand.)
"fc" is a shell built-in for editing and re-running previous commands. The -l flag tells it to display the line rather than edit it, and the -n command tells it to omit the line number. -1 tells it to print the previous line.
For more detail:
$help fc
Shows all block devices in a tree with descruptions of what they are.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.
Brightness indicator to be used in scripts that adjust brightness [especially sys that doesn't support automatically]
Determines the flavor of a shared library by looking at the addresses of its exposed functions and seeing if they are 16 bytes or 8 bytes long. The command is written so the library you are querying is passed to a variable up font -- it would be simple to convert this to a bash function or script using this format.
For example we need find fast where located and described keyword COMMIT_EDITMSG in man files. Here example howto solve it by search with command bzgrep in man files. Generally these files in bz compressed format. You can use another keywords to your search. Common syntax is:
bzgrep -lE keyword1 /usr/share/man/man?/optional-keyword-to-refine*
or
bzgrep -lE keyword1 /usr/share/man/man?/*
where optional-keyword-to-refine is optional and may be omitted but used to speedup search
Of course you may combine other options for bzgrep (its based on grep)
mounts an ISO file to a directory on the target file system
