wildcard-expansion

问题 How do I escape a wildcard expansion in a variable name? CP="lib/*" COMMAND="java $VARIABLES -cp $CP SomeClass" echo $COMMAND Echoing the command always causes wildcard expansion. 回答1: echo "$COMMAND" Using quotes prevents the glob from being expanded. By the way, see "I'm trying to put a command in a variable, but the complex cases always fail!" 回答2: "I'm trying to put a command in a variable, but the complex cases always fail!"

问题 Background This relates to an older stackoverflow question. I was hoping to ask for more details but haven't got the Reputation to write comments yet.

问题 I created a makefile based on the GNU Make the tutorial: https://www.gnu.org/savannah-checkouts/gnu/make/manual/html_node/index.html#SEC_Contents.

The dropped dependency is bin/main.o <-bin/main.o. This makes sense as main.o should not depend on main.o. I searched several sites, including stackoverflow and found some useful

问题 My program has to watch for files which match a mask. The folder name and mask are passed through command line arguments. But the mask is replaced by the first match before I can use it! Double quotes have no effect and other symbols too. I tried using \ or ' to protect the input. However then this symbol will be added to the args, which I do not want. Any idea of how to fix it? public static void main(String[] args) throws IOException { File dir = new File(args[0]); String mask = args[1];
