Not better, but more lightweight (sed instead of perl).

Above command is reduced due to length restriction of less than 256 characters and entity encoding of "Save" command on this page. This is complete command (best without entity encoding):

echo -e '\x2Helo folks\t!\r' | sed "y/\x0\x1\x2\x3\x4\x5\x6\x7\x8\x9\xA\xB\xC\xD\xE\xF\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F\x20/&#9216;&#9217;&#9218;&#9219;&#9220;&#9221;&#9222;&#9223;&#9224;&#9225;&#9226;&#9227;&#9228;&#9229;&#9230;&#9231;&#9232;&#9233;&#9234;&#9235;&#9236;&#9237;&#9238;&#9239;&#9240;&#9241;&#9242;&#9243;&#9244;&#9245;&#9246;&#9247;&#9248;/"

Using the $PIPESTATUS array you can get the results of a command in a sequence of commands piped together. The command above returns the result of grep -o "bob", which is exit result of 1 since no match was made.

Useful if you don't have at hand the ability to automatically create a booklet, but still want to.

F is the number of pages to print. It *must* be a multiple of 4; append extra blank pages if needed.

In evince, these are the steps to print it, adapted from https://help.gnome.org/users/evince/stable/duplex-npage.html.en :

1) Click File ▸ Print.

2) Choose the General tab.

Under Range, choose Pages.

Type the numbers of the pages in this order (this is what this one-liner does for you):

n, 1, 2, n-1, n-2, 3, 4, n-3, n-4, 5, 6, n-5, n-6, 7, 8, n-7, n-8, 9, 10, n-9, n-10, 11, 12, n-11...

...until you have typed n-number of pages.

3) Choose the Page Setup tab.

- Assuming a duplex printer:

Under Layout, in the Two-side menu, select Short Edge (Flip).

- If you can only print on one side, you have to print twice, one for the odd pages and one for the even pages.

In the Pages per side option, select 2.

In the Page ordering menu, select Left to right.

4) Click Print.

col() { awk '{print $('$(echo $* | sed -e s/-/NF-/g -e 's/ /),$(/g')')}'; }

Something I do a lot is extract columns from some input where cut is not suitable because the columns are separated by not a single character but multiple spaces or tabs. So I often do things like:

... | awk '{print $7, $8}'

... which is a lot of typing, additionally slowed down when typing symbols like '{}$ ... Using the simple one-line function above makes it easier and faster:

... | col 7 8

How it works:

The one-liner defines a new function with name col

The function will execute awk, and it expects standard input (coming from a pipe or input redirection)

The function arguments are processed with sed to use them with awk: replace all spaces with ,$ so that for example 1 2 3 becomes 1,$2,$3, which is inserted into the awk command to become the well formatted shell command: awk '{print $1,$2,$3}'

Allows negative indexes to extract columns relative to the end of the line.

If we've many files containing (?, ?, ?, ?, ? ) characters instead of ?, ?,... etc,...

we can ue this simple command line running a sed command inside a for loop searching for files containing that characters.

Hope u like it! Enjoy! ;)

In this example I am returning all the files in /usr/bin that weren't put there by pacman, so that they can be moved to /usr/local/bin where they (most likely) belong.
