在bash中,我怎样才能使这样的结构起作用:
if (cp /folder/path /to/path) && (cp /anotherfolder/path /to/anotherpath)
then
echo "Succeeded"
else
echo "Failed"
fi
if应该测试$?返回每个命令的代码并将它们与&&。
联系起来我怎样才能在Bash中做到这一点?

另一种方式:
cp /folder/path /to/path && cp /anotherfolder/path /to/anotherpath && {
echo "suceeded"
} || {
echo "failed"
}
我测试了它:
david@pcdavid:~$ cp test.tex a && cp test.aux b && { echo "haha"; } || { echo "hoho"; }
haha
david@pcdavid:~$ cp test.ztex a && cp test.aux b && { echo "haha"; } || { echo "hoho"; }
cp: cannot stat `test.ztex': No such file or directory
hoho
david@pcdavid:~$ cp test.tex a && cp test.zaux b && { echo "haha"; } || { echo "hoho"; }
cp: cannot stat `test.zaux': No such file or directory
hoho
