| 2 |  Quick Linux Tip 🐧
In Linux, the pipe(|) operator is very useful if you want to redirect the output of one command to serve as input to the next for further processing:
$ cat data.conf | grep "No such file"
However, this does not redirect the errors. So, if the file does not exist, the grep command above will not return a match.
What if you want to redirect and process both errors and normal output🤔
This is where this "|&" redirection operator comes in handy.
This operator sends both the standard output (stdout) and standard error (stderr) of the first command over a pipe to the standard input (stdin) of the second command. Take a look at this example:
$ cat data.conf |& grep "No such file"
Notice the difference, the grep command was able to get a match.
The "|&" operator in bash is a shorthand for the "2>&1 |" redirection operator.
$ cmd-1 2>&1 | cmd-2 | 18 116 |

• $1, $2, $3, ...
These are the positional parameters, representing arguments passed to the script or function. $1 is the first argument, $2 is the second, and so on.
• "$@"
An array-like construct containing all positional parameters. Each parameter is treated as a separate quoted string, preserving spaces.
• "$*"
Expands all positional parameters as a single string, separated by the current Internal Field Separator (IFS).
• $#
The number of positional parameters passed to the script or function.
• $-
Displays the current shell options as a string (e.g., himBH for interactive, monitor mode, etc.).
• $$
The process ID (PID) of the current shell instance, not any subshell it may invoke.
• $_
Holds the last argument of the previous command or the absolute path of the shell script executed at startup.
• $IFS
The Internal Field Separator, used to split input into fields during expansion. Defaults to spaces, tabs, and newlines.
• $?
The exit status of the last executed command. A value of 0 typically means success, while non-zero indicates an error.
• $!
The PID of the most recently executed background command.
• $0
The name of the script or shell being executed, including its path if run with one. | 12 323 |
