Run Range
World's simplest linux tool
This online utility implements a brand new Linux command called range. This command combines the head and tail commands and outputs a range of characters, words, or lines from the given data. The range indexes can be both positive or negative numbers (if they are negative, the range is extracted from the end of data). Created by Linux experts from team Browserling.

What is a Run Range?
learn more about this tool
This browser-based JavaScript program implements a new Linux command called range. A common operation in Linux is to extract a range of data from a file. We solved this problem quickly and efficiently by creating range. You can simply specify the start and end positions of the range and extract the text piece that falls in this range. The new command has three modes for finding and printing ranges. The line-range matches (and prints) all lines from the starting line position to ending line position. The word-range matches (and prints) all words between the starting word position and ending word position. The character-range matches (and prints) all symbols from the starting character index to ending character index. The range indexes can be either positive or negative integers. Positive indexes count lines/words/characters from the beginning of text and negative positions count lines/words/characters from the end of text. For example, the range 5 to 10 will match either lines 5 to 10 (inclusive), or 5th word to 10th word, or 5th char to 10th char. The range 5 to -10 will match from the 5th line to the 10th line from the end (same for words and chars). The range -15 to -5 will match lines from the 15th line from the end to the 5th line from the end. If the start position field is left blank, then it's set to 1 and the extraction will start at the first symbol at the beginning of text. If the end field is left blank, then the extraction will continue to the last symbol of the end of text. For extra convenience, we've also added an option that can skip blank lines in the line range mode. Tuxabulous!
Run Range examples

In this example, we're using our browser version of the Linux range command to extract certain titles from a list of the all time greatest books. To do this, we select the line printing option and enter the range from 4 to 8. We also exclude blank lines from the output by unchecking the "Output Empty Lines" option.

Get a Range of Characters
In this example, we slice a part of Leo Tolstoy's quote and extract a range of characters from it. We set the start of the range to a positive value of 7 and the end of the range to a negative value of -13. This way, the output text is a passage that starts at the beginning at the 7th character position and goes to the 13th position from the end (this is what the minus sign in -13 means – count 13 positions from the end).

Match Till End
In this example, we switch on the word range mode and print the last nine words from an interesting fact about people. In the start position field, we enter the value -9, which anchors the starting position to the ninth word from the end, and we leave the end position empty, which means match all words till the end.
