The most obvious situation where you might need to quote a string is with the echo command, which just takes its arguments and prints them to the standard output, What is the point of this? As you will see in later chapters, the shell does quite a bit of processing on command lines—most of which involves some of the special characters listed in Table 1

Example_snippet/controller/utility/_character.js/ $ echo 2 * 3 > 5 is a valid in. . .
$ echo 2 * 3 > 5 is a valid inequality.
Step 2 continued with $ echo '2 * 3 > 5 is a valid i. . .
$ echo '2 * 3 > 5 is a valid inequality.'
Step 3 continued with $ echo '2 * 3 > 5' is a valid . . .
$ echo '2 * 3 > 5'
is a valid inequality.

Escape each single special symbol with a backslash (as in \[abc\]_\[x\|y\]) or,Double-quote the entire argument (as in "[abc]_[x|y]"),,Quote each argument separately (if they need quoting) so they are interpreted as independent arguments

Example_snippet/controller/utility/_character.js/ $ printf %s 'spaces are not . . .
$ printf % s 'spaces  are  not  interpreted away
neither are new lines
nor variable names $TESTING
nor square brackets[TESTING]
nor pipe characters or redirection symbols | > <
   nor the semicolon;
nor backslashes\ a\ b\ c\\
the only thing that does not work is the single quote itself
Step 2 continued with $ printf '%s\n' '[ Don'"'"'t w. . .
$ printf '%s\n'
'[ Don'
't worry, be happy! ]' [Don 't worry, be happy! ]
   $ printf '%s\n'
   '[ Don'\
   t worry, be happy!
' [Don 't worry, be happy! ]
