我试图写一个简单的bash脚本,将复制一个文件夹的全部内容,包括隐藏的文件和文件夹到另一个文件夹,但我想排除某些特定的文件夹。我怎么才能做到呢?

你可以在-prune选项中使用find。
一个来自man find的例子:
cd /source-dir find . -name .snapshot -prune -o \( \! -name *~ -print0 \)| cpio -pmd0 /dest-dir This command copies the contents of /source-dir to /dest-dir, but omits files and directories named .snapshot (and anything in them). It also omits files or directories whose name ends in ~, but not their con‐ tents. The construct -prune -o \( ... -print0 \) is quite common. The idea here is that the expression before -prune matches things which are to be pruned. However, the -prune action itself returns true, so the following -o ensures that the right hand side is evaluated only for those directories which didn't get pruned (the contents of the pruned directories are not even visited, so their contents are irrelevant). The expression on the right hand side of the -o is in parentheses only for clarity. It emphasises that the -print0 action takes place only for things that didn't have -prune applied to them. Because the default `and' condition between tests binds more tightly than -o, this is the default anyway, but the parentheses help to show what is going on.

类似于Jeff的想法(未经测试):
find . -name * -print0 | grep -v "exclude" | xargs -0 -I {} cp -a {} destination/
EXCLUDE="foo bar blah jah"
DEST=$1
for i in *
do
for x in $EXCLUDE
do
if [ $x != $i ]; then
cp -a $i $DEST
fi
done
done

使用焦油和管道。
cd /source_directory
tar cf - --exclude=dir_to_exclude . | (cd /destination && tar xvf - )
您甚至可以跨ssh使用此技术。
使用 rsync:
rsync -av --exclude='path1/to/exclude' --exclude='path2/to/exclude' source destination
注意,使用source和source/是不同的。后面的斜杠表示将文件夹源的内容复制到目标。如果没有后面的斜杠,它意味着将文件夹源复制到目标。
或者,如果要排除很多目录(或文件),可以使用——exclude-from=FILE,其中FILE是包含要排除的文件或目录的文件名。
——exclude也可以包含通配符,例如——exclude=*/.svn*
