Since you are talking bout "commands" I presume you are talking bout the pipes you use in a command line

if so the command to use is  "|" without the codes. Thats the pipe charcater which you can get by typing shift+\

e.g  say you have to count the number of words in a file

you can do

cat filename | wc -w

here your file content is piped to the word count program 'wc'
 what internally the system ( shell ? ) does is that it creates a pipe between your cat and wc command
effectively connecting the standard output of 'cat' to the standard input of 'wc'. The shell takes care of all the inter process communication or whatever
