You want to delete text from a text file? If so, you'll want to open and editor like vi or vim and delete the lines.

Code:

vi yourfile

To get a list of vi/vim commands visit this site. Hope that answered your question.

What kind of content deletion do you have in mind? Want the script to search and remove certain keywords? Or delete lines that include particular words? You need to be more specific if you want concrete help.

Sed is usually used for editing files. The name stands for Serial EDitor.
For tabular text, awk is often used.
