我怎样才能回应编译的状态？

Question

I've written a small command to compile every C file in every directory , I have:

find $1 -type f -name '*.c' -exec sh -c 'gcc  {} -o $(dirname {})/$(basename {} .c)' \;

and it compiles everything, but I would like it to display the status of each file being compiled, and display when each one is finished, but I'm really out if ideas.

If anyone could help I would love that!

Answer 1

You can echo $? after running gcc which will show you its return status. If a file compiles it will be 0 , if it doesn't it will be 1 I think. But there may be different return values for different errors, I'm not sure about this.

Answer 2

This is likely an academic issue, but using {} multiple times in the argument to find is not portable. Similarly, expecting {} to expand to the filename when it is not the only string in the argument is not portable. (That is, the entire argument must be exactly {} ). Also, using gcc explicitly rather than make is probably the wrong approach. That said, you can simply echo each path that successfully compiles:

find $1 -type f -name '*.c' -exec sh -c 'gcc $0 -o $(dirname $0)/$(basename $0.c) &&
    echo $0' {} \;

Also, if you can simplify with bash:

find $1 -type f -name '*.c' -exec bash -c 'gcc $0 -o ${0%.c}.o && echo $0' {} \;
