#include <stdio.h>
int main(int argc,char** argv) {
while (*++argv) printf("%s\n",*argv);
return 0;
}
I've had trouble passing command line arguments with ampersands in them.
For example, I would expect:
*test &0 &0,&1 &9,&1 &-,&1 "&0,&1" &a,&b
&0
&0,&1
&9,&1
&-,&1
&0,&1
&a,&b
*
but get:
*test &0 &0,&1 &9,&1 &-,&1 "&0,&1" &a,&b
&0
&0
&9
&-
&a,&b
*
(The argument in double quotes is missing completely.) The arguments seem to be
confused with redirection file descriptors, 2>&1 2>&- etc.
With just small changes to an argument, it can be quite unpredictable as to
what's going to be passed through. The only way I've found to get what I
originally wanted was to protect the first ampersand with both "" and \
*test "\&0,&1"
&0,&1
*
