† By default xargs will pass multiple lines of input to a single command, appending them all to its argument list. But specifying -I % makes xargs put the input at the specified place in the command, and only put one line there at a time, running echo as many times as required.
You need to use the >> to append text to end of file. It is also useful to redirect and append/add line to end of file on Linux or Unix-like system.
The ^ character is what instructs the sed command to add a character to the beginning of each line. Here's the syntax for adding a space to the beginning of each line using sed . Alternatively, use the -i option with the sed command to edit a file in place.
There are many ways:
sed: replace $ (end of line) with the given text.
$ sed 's/$/ | COUNTRY/' file india | COUNTRY sudan | COUNTRY japan | COUNTRY france | COUNTRY awk: print the line plus the given text.
$ awk '{print $0, "| COUNTRY"}' file india | COUNTRY sudan | COUNTRY japan | COUNTRY france | COUNTRY Finally, in pure bash: read line by line and print it together with the given text. Note this is discouraged as explained in Why is using a shell loop to process text considered bad practice?
$ while IFS= read -r line; do echo "$line | COUNTRY"; done < file india | COUNTRY sudan | COUNTRY japan | COUNTRY france | COUNTRY If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
