For one thing, alike the best accessible commands accept a lot added options than abounding Linux users anytime get about to using. And there are some beneath accessible commands that action some altered features. In this post, we’ll both at commands for examination the capacity of files and options for dressmaking those angle to bigger baby to your needs.

The cat command sends the absolute capacity of argument files to your terminal window for viewing. In fact, if you blazon “cat” followed by the name of a book with bags of lines, those curve will adept by your window so fast, you won’t be able to accomplish out abundant added of it than the aftermost screenful of text. Yet, as accustomed as the cat command is to Linux users, alike this basal command provides a lot of advantageous options such as calculation the curve in the achievement that abounding of us acceptable haven’t anytime used. To aggrandize on that, not alone can you cardinal lines; you accept some choices in how you do the numbering.

Numbering every band looks like this:



You can additionally cardinal alone curve with content. Note that a band absolute alone blanks is not advised “empty” for this command and would be numbered.

The cat command allows you to avoid again bare curve with the -s option, but you accept to add addition command to abolish blanks curve altogether.

To avoid all of the bare lines, aloof aqueduct the achievement from cat to a grep command as follows. The dot (.) matches argument including bare characters, so it will affectation curve that accommodate alone blanks and alone attending empty.

The -E optoin provides a beheld cue to appearance whether there are added blanks at the ends of curve by afraid a $ at the end of every line.

With -A, you get both the $ characters at the end of anniversary band and tabs assuming up as ^I rather than abandoned space.

The arch and appendage commands appearance the acme or cheers of files and absence to ten lines. You can specify a altered cardinal of curve to appearance by application strings like -3 (show 3 lines) or -11 (show 11 lines). The appendage command works the aforementioned way as arch but displays the cheers of files rather than the tops.

You can additionally amalgamate arch and appendage commands to appearance argument amid the acme of cheers of files. You aloof accept to aces your starting point and how abounding curve you appetite to see. In this example, the command would affectation the additional hundred curve in a book and, with cat’s help, calculation those lines.

The added command is an accessible best for browsing through a file’s agreeable a screenful at a time while beneath adds the adeptness to move up and bottomward in a book by application the up and bottomward keyboard arrows so that you can alpha scanning and again aback up in the file.

The od (octal dump) command allows you to appearance a book both as accustomed argument and as a alternation of ASCII ethics (i.e., how that argument is absolutely encoded in the files). As you can see in the archetype below, the numbered curve appearance the numeric ASCII ethics and the alternating curve appearance the argument and non-printable characters.

Notice how newline characters are apparent as n (octal 012) and tabs are apparent as t (octal 011).

One of the abnormally accessible uses of the od command is for attractive at non-text files for advice that identifies the book types. In this case, we see the JFIF (JPEG Book Interchange Format) characterization that identifies it as a jpg book to commands like book that address on book types. There’s a lot of added advantageous advice in there as well, abnormally if you’re analytical about how these files are formatted.

In this abutting command, we are attractive at the alpha allocation of a jpg file.

If we were to ask the book command for advice on this angel file, we ability see article like this. The book command is affairs all this anecdotic advice from abstracts at the alpha of the file.

If you are bound to the command band and appetite to get an abstraction what a accurate angel book contains, you can use a apparatus like jp2a (jpeg to ascii) to accord you a appearance rendition. How apparent the angel will be in this architecture depends on the file. Don’t apprehend abundant as the adaptation of the angel you will see is activity to put “low res” to the test! This one’s a actual low resolution emperor penguin.

There are absolutely a few commands on Linux for analytical the agreeable of files in assorted ways. Some accept options which can prove actual accessible back you charge to dispense book contents. Others are aloof … interesting.
