In Bash, you can find out the exit code of each piped command by checking the exit code of the last command in the pipe.<\/p>\n

To do this, you can use the special shell variable $?<\/code> which contains the exit code of the last executed command.<\/p>\n

For example, consider the following command:<\/p>\n

\n
<\/div>\n
command1 | command2 | command3
\n<\/code><\/div>\n<\/div>\n

To find the exit code of each command, you can add the following lines after the piped commands:<\/p>\n

\n
<\/div>\n
command1 | command2 | command3<\/p>\n

echo<\/span> \"Exit code of command1: $?\"<\/span>
\necho<\/span> \"Exit code of command2: $?\"<\/span>
\necho<\/span> \"Exit code of command3: $?\"<\/span>
\n<\/code><\/div>\n<\/div>\n

The exit code of each command will be displayed in the output.<\/p>\n

Note: The exit code of command1<\/code> can only be checked after the entire pipeline of commands has completed execution.<\/p>\n","protected":false},"excerpt":{"rendered":"
