Suppress echo of command invocation in makefile?

Question

I wrote a program for an assignment which is supposed to print its output to stdout. The assignment spec requires the creation of a Makefile which when invoked as make run

Answer 1

You can also use .SILENT

.SILENT: run
hi:
     echo "Hola!"
run:
     java myprogram

In this case, make hi will output command, but make run will not output.

Answer 2

Even simpler, use make -s (silent mode)!

Answer 3

The effect of preceding the command with an @ can be extended to a section by extending the command using a trailing backslash on the line. If a .PHONY command is desired to suppress output one can begin the section with:

@printf "..."

Answer 4

Add @ to the beginning of command to tell gmake not to print the command being executed. Like this:

run:
     @java myprogram

As Oli suggested, this is a feature of Make and not of Bash.

On the other hand, Bash will never echo commands being executed unless you tell it to do so explicitly (i.e. with -x option).
