Sed

sed is a unix command for stream data editor.

Special Characters

When dealing with special characters, use a different set of separators. For example: when dealing with ', use the following command:

sed "/'/d" OriginalTextualContent.txt > NoSeparator.txt 

Two or more replacement rules

If one needs to replace more than one set of characters, one can use the following expression:

sed -e "/'/d" -e "s/,/|/g" OriginalTextualContent.txt > NoSeparator.txt 

Note the two -e prefixes. These prefixes defines the multiple substitution expressions.
