Shell Programming and Scripting

Hi

I want to use echo command as below

i need output like below :

Code:

echo 'dir=' $1 ' dir|file|home' pp13dff

Output

Code:

dir=pp13dff dir|file|home

That isn't the way echo works. You could put the echo in a shell script and invoke the script with the last parameter you're giving to echo as a parameter to the script, but the following is probably closer to what you want:

Code:

var=pp13dff
printf "dir=%s dir|file|home\n" "$var"

If pp13dff isn't in a variable this doesn't make much sense. If you have the string you want to echo when writing the echo, why not just use:

Code:

echo 'dir=pp13dff dir|file|home'

I know my friend ,

But I want use awk or echo command so i can run with single line//

Thanks for your time men!!!

So, if you want that output from echo, use the code I showed you in my last message. If you want a single line awk program to do it, try:

Code:

awk 'END {print "dir=" var " dir|file|home"}' var=pp13dff /dev/null

It sounds very much like you don't understand the concepts of a shell and positional parameters. If you need help with these basic concepts, you should probably be posting questions in the UNIX for Dummies Questions & Answers forum instead of the Shell Programming and Scripting forum (which assumes more advanced knowledge of basic shell operations and parameter passing).

The command that was given to you was a single line.

Even better, it's a single-line shell builtin.

I have no idea what you'd expect awk or echo to help with here.
