我有一个名为 hitlist.txt 的txt文件（通常会更新），其中包含一个单词/字符串列表，我想grep一个目录，反对...喜欢：
# This is just a comment and will not be part of the search
* Blah - this is a category
foo
bar
sibilance
# A new category
* Meh - another category
snakefish
sex panther
我的列表通常是＆gt; 100个字符串，每个字符串都在它自己的行上。今天，由于截止日期，我只是通过列表并为每个单词执行以下命令：
find -iname "*" -type f -print0 | xargs -0 -HniI "foo" >> results.txt
如上面的命令所示，我对文件路径和名称以及包含匹配文本的行感兴趣。文件中有多个类别列表（由*表示），我希望能够针对一个，多个或所有类别运行我的脚本。
我还希望能够关闭-i标志（区分大小写）作为选项。我有一个脚本递归查找/列出目录中的所有文件，以及我上面使用的命令。最后，如果需要，可以完全更改 hitlist 格式。

设置ghl()（ g 代表 h l ist ）shell函数来完成工作，（取决于 GNU grep的{{1}}开关，再加上一个-o循环），输出是一个来自 hitlist.txt （或sed）的单词列表：
<filename>将# usage ghl <glob> <filename>
ghl() { grep -o '\* '"$1"' -' "$2" | grep -o '[[:alpha:]]*' | \
while read x ; do \
sed -n '/\* '"$1"'/{:show ;n;/^[^ ]/{p;b show;}}' "$2" ; \
done ; }
的单词列表输出与“ghl”通配符（与 Blah 类别匹配）加载到.*ah，加上一些< em> ad hoc grep -f - process substitution生成输入文本：
bash输出：
ghl '.*ah' hitlist.txt | grep -i -f - <(echo bar) <(echo foo) <(echo Foo)
上面的第二个/dev/fd/63:bar
/dev/fd/62:foo
/dev/fd/61:Foo
可以根据需要传递开关（参见grep）。示例，同样的事情，但区分大小写（即删除man grep开关）：
-i输出，（注意缺少大写项目）：
ghl '.*ah' hitlist.txt | grep -f - <(echo bar) <(echo foo) <(echo Foo)
由于/dev/fd/63:bar
/dev/fd/62:foo
已经有了处理递归搜索的选项，其余的只是根据需要添加开关。

你的问题非常模糊，但我想象这或多或少都是你想要的。
awk -v cat='Blah|Meh' 'NR==FNR && /^#/ { next } # Skip comments
NR==FNR && /^\*/ { if ($0~cat) c=1; else c=0; next }
NR==FNR { if(c) a[$0]=1; next }
lower($0) in a { print FILENAME ":" FNR ":" $0 }' Hits.txt files to search
弄清楚如何有选择地禁用lower()并绑定它以从Hits.txt读取find以外的文件名列表应该是相当明显的。

这就是我最终的结果：
命中列表格式：
# MEH
never,going,to give,you up
# blah
word to,your,mother
脚本：
# Set defaults
OUTPUT_FILE="hits.txt"
HITLIST_FILE="hitlist.txt"
# Hold on to the args
ARGLIST=($*)
# Declare any functiions
help ()
