This command will display the file, but you can change 'cat' to anything else (type 'n' when prompted to cancel the command or anything else to proceed). . Some hints for newbies: type
unset barto make 'bar' function annihilated. For permanent usage you can put this (bar) function in your .bashrc (for bash) or in .profile (for sh). With:. ~/.bashrcyou can get all new inserted functions in .bashrc (so the function 'bar' or whatever name you choose) immediately available.

This command will take the output of curl and read it line by line, skipping a step in downloading the file then parsing it. You can then parse each line, or only print the lines that contain certain works using if statements, or whatever you can come up with. Or you can change IFS and use it to parse based on separators other than newline.
0while read line; do echo $line;done < <(curl -s <URL of file to read>) -

I just needed to store the LAN IP (for ipv4) in a variable for a specific task in a bash script. I figured I'd share. I sent it to a variable with VAR=$(stuff) and used it later on. I put the exit 0 in the if statement to make it so that it breaks if there are more than one IPv4 addresses assigned. I only wanted the first one. Edit: Bear in mind, my network mask is a double digit number so if you have a smaller nw mask you'd need to edit the sed statement. Show Sample Output
0ip addr show | grep "inet " | while read INET IP TRASH; do if [ $IP != "127.0.0.1/8" ]; then echo $IP; exit 0; fi; done | sed s:/[1-9][1-9]:"": -
Retrieves AS route prefixes for IPv4 and IPv6, aggregates the routes to the minimal set, and adds netfilter rules to reject them.

0ASN=32934; for IP in 4 6; do whois -h riswhois.ripe.net \!${IP/4/g}as${ASN} | sed -n '2 p' | tr \ \\n | aggregate${IP/4/} | while read NET; do ip${IP/4/}tables -I INPUT -S ${NET} -j REJECT; done; done -
Requires mpc command line client Assumes only one output with "Local" in the name

The given file may contain any kind of characters. This is compatible for most simple mathematical operation. For the first number found, it will be replaced by the result of a factor operation of 1000. To change the filename or multiplactor or number regular expression, change the first fixed values.
