Sort lines in a file

To use a script, cut and paste the code from the light green or blue box into a terminal window, change the bold, red text as needed, and hit Enter.

See More Information for notes on using these tools.

Sort a file alphabetically

See General Sorting Notes for details on sorting order.

Sort alphabetically, in ASCENDING order (sort_alpha_asc)

Sort the lines in the file in ascending alphabetical order.

General Sorting Notes

The tools as written will sort the given file1 and send the result to the given output file. In fact, any number of input files can be used (before the '>' sign), but just one output file. Change the filenames as you wish.

Sorting order: Note that 100 will come before 20 when sorting alphabetically, because 1 comes before 2. Also, lower-case letters come after all of the upper-case letters (i.e., a will come after Z), unless case-sensitive sorting is used. (i.e., when sorting in ascending order, "arabidopsis" will come after "Zebrafish"), unless case-insensitive sorting is used. See the examples below for demonstrations of these rules.

Duplicates will not be eliminated. That is, if the same line appears five times in a file, it will appear five times (in a row) in the output file.

General Scriptome Notes

Scriptome tools are in blue or green boxes. Cut and paste the text of the tool into a terminal window. Then edit the line as needed. Things that will often need to be edited are highlighted in red. Input and output filenames will almost always need to be changed.

All scripts that work on tabular data assume the data is tab-separated. Use a Change script to change, e.g., comma-separated data to tab-separated before using these scripts.
