Check These Out
Sometimes I need to create a directory of files to operate on to test out some commandlinefu I am cooking up. The main thing is the range ({1..N}) expansion.
cp options:
-p will preserve the file mode, ownership, and timestamps
-r will copy files recursively
also, if you want to keep symlinks in addition to the above: use the -a/--archive option
In this case searches for where .desktop files are stored. The resulted is a sorted list of the top directories containing such files.
I often find the need to number enumerations and other lists when programming. With this command, create a new file called 'inputfile' with the text you want to number. Paste the contents of 'outputfile' back into your source file and fix the tabbing if necessary. You can also change this to output hex numbering by changing the "%02d" to "%02x". If you need to start at 0 replace "NR" with "NR-1". I adapted this from http://osxdaily.com/2010/05/20/easily-add-line-numbers-to-a-text-file/.
The same as the other two alternatives, but now less forking! Instead of using '\;' to mark the end of an -exec command in GNU find, you can simply use '+' and it'll run the command only once with all the files as arguments.
This has two benefits over the xargs version: it's easier to read and spaces in the filesnames work automatically (no -print0). [Oh, and there's one less fork, if you care about such things. But, then again, one is equal to zero for sufficiently large values of zero.]
Say you just typed a long command like this:
$ rsync -navupogz --delete /long/path/to/dir_a /very/long/path/to/dir_b
but you really want to sync dir_b to dir_a. Instead of rewriting all the command line, just type followed by , and your command line will read
$ rsync -navupogz --delete /very/long/path/to/dir_b /long/path/to/dir_a
`aria2c` (from the aria2 project) allows. Change -s 4 to an arbitrary number of segments to control the number of concurrent connections. It is also possible to provide multiple URLs to the same content (potentially over multiple protocols) to download the file concurrently from multiple hosts.
README: This require you to login on facebook with elinks without using '-dump' first time and when you have logged in you will then be able to dump all data from facebook without any advanced combos, dump is all you need for see all your friends newsfeed or whatever you wish to view in cli/terminal. Facebook is just an example, same requirements for all websites that have a login form.
