How to force awk not to print a newline

To force awk not to print a newline at the end of the output, you can use the ORS (Output Record Separator) variable. By default, awk adds a newline character to the end of each output record. You can use the ORS variable to change this separator to something else, or to suppress it entirely.

For example, to suppress the newline character at the end of the output, you can use the following awk command:

awk 'BEGIN {ORS=""; print "Hello, World!"}'

This will print the string "Hello, World!" without a newline character at the end.

Alternatively, you can use the printf function to control the output format more precisely. The printf function allows you to specify a format string that determines how the output will be printed, including the newline character at the end. For example, to print the string "Hello, World!" without a newline character at the end, you could use the following awk command:

awk 'BEGIN {printf "Hello, World!"}'
