2500+ students have taken this innovative project-based data learning course (includes video lectures). It demonstrates the use of Bash shell (Bash, sed and awk including RegEx) in processing textual data. It can help to learn to sort, search, match, replace, clean and optimize various aspects of data with Bash Shell. The target audience (students, researchers, scientists, journalists, data miners, developers) didn't have to go through any tough learning curve. This course also should have helped RedHat, SuSE and Ubuntu Linux learners and Data Science enthusiasts.  Regularly updated, new projects to come!

Learn Data Science with Bash Shell

We have already learned REGEX. Let's learn the use of `SED + REGEX` by using a couple of practical exmaples:

**Example 1:**  match patterns and REGEX (`\!.*`)

~~~~~~
$ sed '/\!/s/\!.*//g' datafile
~~~~~~

In this example, if the line matches with the pattern `“!“`, then it replaces all the characters from `“!”` with an empty char.


**Example 2:** use REGEX to delete the last `x` characters

~~~~~~
$ sed 's/...$//' datafile
~~~~~~

This sed example deletes last 3 characters from each line.


**Example 3:** use REGEX to eliminate comments  (`#`)

~~~~~~
$ sed -e 's/#.*//'  datafile
~~~~~~

This sed example deletes last 3 characters from each line.


**Example 4:** use REGEX and  eliminate Comments (`#`) as well as the empty lines

~~~~~~
$ sed -e 's/#.*//;/^$/d'   datafile
~~~~~~
