Sorting a file with pipe-delimited fields using unix sort

Hi All

Today a simple command to sort a file with pipe-delimited fields.

My file is :

EG|TW|SA|04/05/2009||
EG|NA|EN|02/05/2003||
SS|TW|SA|04/05/2009||
CD|DC|TI|30/12/2004||
ET|EG|TI|02/05/2003||
NI|SS|EN|18/02/2005||
EG|ET|TI|02/05/2003||
IN|ET|TI|21/09/2000||
SS|SS|SA|28/02/2005||
IN|PR|EN|01/11/2003||
PR|TW|SA|04/05/2009||
SS|EN|TN|18/02/2005||
EG|DC|TI|17/09/2010||
EG|EI|SA|04/08/2005||
NA|IN|SA|21/09/2000||

To sort all records by third field.
I can use these simple command :

sort -t"|" -k 3 [file_name]

Where -t is an option where u can explain field separator and with -k you can explain third field.

Stay tuned.
