我有一个csv文件(list.csv),其中包含类似的内容:
<form id="myform" method="POST" ng-submit="submitForm()">
<input type="text" name="city" id="city" ng-model="city">{{ city }}
<button type="submit">Click Here</button>
</form>
我有另一个文件(delete.txt):
"1","10","1","2"
"2","22","20","2"
"3","33","5","2"
"4","36","225","2"
"5","36","225","2"
我想从delete.txt文件中删除包含ID的每一行。 在我的例子中,我想显示:
"1"
"4"
我该怎么做?谢谢:))

一次性使用grep(如果要查看使用的查询,可以在末尾添加echo "$arg"
):
#!/bin/bash
arg=""
for i in `cat delete.txt`; do
if [ -n "$arg" ]; then
arg="$arg\|^$i"
else
arg="^$i";
fi
done;
grep -v "$arg" input.txt

你可以试试这个:
< delete.txt xargs -I % sed -i '/%/d' list.csv
它读取delete.txt中的所有行,并传递给sed进行删除。
