Hi,
I have the following code in the make file

Code:

	echo "      swremove \`swlist -l product | grep someproduct| awk '{print $1}'\` ">>filename

i want

Code:

swremove 
 `swlist -l product | grep someproduct|awk '{print $1}'`

to appear. Please can any one help how to suppress $??... I tried \$ and with double qoutes and all.but it didnt work....

Backslash works for me here. Are you using some atrocious c shell?

Code:

vnix$ echo "      swremove \`swlist -l product | grep someproduct| awk '{print \$1}'\` "
      swremove `swlist -l product | grep someproduct| awk '{print $1}'`

vnix$

... Or by "in the make file" you mean this is in a makefile? Then you also need to double the dollar sign (but then also the output would be different than what you are reporting).

Code:

vnix$ cat Makefile
fun:
	echo "      swremove \`swlist -l product | grep someproduct| awk '{print \$$1}'\` "

vnix$ make
echo "      swremove \`swlist -l product | grep someproduct| awk '{print \$1}'\` "
      swremove `swlist -l product | grep someproduct| awk '{print $1}'`

And of course, *bling*, this:

Code:

grep someproduct| awk '{print \$$1}'

... gets you the prestigious "useless use of grep | awk" award.

Code:

awk '/someproduct/ { print \$$1}'
