/* Help to copy the thing properly quoted for the shell safety.
|
|
* any single quote is replaced with '\'', any exclamation point
|
|
* is replaced with '\!', and the whole thing is enclosed in a
|
|
* single quote pair.
|
|
*
|
|
* For example, if you are passing the result to system() as an
|
|
* argument:
|
|
*
|
|
* sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1))
|
|
*
|
|
* would be appropriate. If the system() is going to call ssh to
|
|
* run the command on the other side:
|
|
*
|
|
* sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1));
|
|
* sprintf(rcmd, "ssh %s %s", sq_quote(host), sq_quote(cmd));
|
|
*
|
|
* Note that the above examples leak memory! Remember to free result from
|
|
* sq_quote() in a real application.
|
|
*
|
|
* sq_quote_buf() writes to an existing buffer of specified size; it
|
|
* will return the number of characters that would have been written
|
|
* excluding the final null regardless of the buffer size.
