Hi, Although echo is sufficient most of the time, my understanding is that printf may be better for certain situations (for example, formatting the width of a number). The manual doesn't explicitly mention in what situations it is better to use printf than to use echo. I think that this might have been compared before, but I don't find it. Could you please let me know when to use printf instead of echo?
In particular, I want to print a string that has single quote, double quote and dollar character. I could use " to enclose such string and add '\' to escape " and $ in the string. But I can't use ' in to enclose the string. It is still inconvenient to have too many escape characters. I'm wondering what is the best way to print such string. echo "\$XX\"'" # this works. echo '$XX"\'' #this doesn't work. -- Regards, Peng
