+
+Use with caution! Its a plain wrapper around **sed** and the input is not sanitized.
+
+
+-----
+
+**What it does**
+
+Changes every line of a text file according to a given regular expression.
+
+-----
+
+**Syntax**
+
+Use the **sed**-syntax -> **s/find-pattern/replace-pattern/**
+
+**Example**
+
+- **s/x/-/** Replace all **x** with **-**.
+
+- **s/_.*//** Splits a string after **_** and replaces the rest with nothing.
+- **s/[^_]*_*//** Splits a string after **_** and replaces the first part with nothing.
+
+- **s/\\s.*//** Splits a string after whitespaces and replaces the rest with nothing.
+- **s/\\S*\\s*//** Splits a string after whitespaces and replaces the first part with nothing.
