删除文件-linuxcli中的字符串文件-Deletefileswithstringfoundinfile-linuxcli

49  

For safety I normally pipe the output from find to something like awk and create a batch file with each line being "rm filename"

为了安全起见，我通常将输出从find输出到awk，并创建一个批处理文件，其中每一行都是“rm filename”

That way you can check it before actually running it and manually fix any odd edge cases that are difficult to do with a regex

这样，您就可以在实际运行它之前检查它，并手动修复使用regex难以处理的任何奇边情况

find . | xargs grep -l email@domain.com | awk '{print "rm "$1}' > doit.sh
vi doit.sh // check for murphy and his law
source doit.sh

@Martin Beckett posted an excellent answer, please follow that guideline

@Martin Beckett发布了一个很好的答案，请遵循这个指导

solution for your command :

您的命令的解决方案:

grep -l email@domain.com * | xargs rm

Or

或

for file in $(grep -l email@domain.com *); do
    rm -i $file;
    #  ^ prompt for delete
done

You can use find's -exec and -delete, it will only delete the file if the grep command succeeds. Using grep -q so it wouldn't print anything, you can replace the -q with -l to see which files had the string in them.

您可以使用find的-exec和-delete，只有在grep命令成功时，它才会删除文件。使用grep -q，这样它就不会打印任何东西，您可以用-l替换-q，以查看哪些文件中有字符串。

find . -exec grep -q 'email@domain.com' '{}' \; -delete

Despite Martin's safe answer, if you've got certainty of what you want to delete, such as in writing a script, I've used this with greater success than any other one-liner suggested before around here:

尽管Martin给出了安全的答案，但如果您确定要删除的内容，比如在编写脚本时，我使用它的成功程度超过了之前这里提到的任何一行代码:

$ find . | grep -l email@domain.com | xargs -I {} rm -rf {}

But I rather find by name:

但我宁愿按名字来找:

$ find . -iname *something* | xargs -I {} echo {}

find . | xargs grep -l email@domain.com

how to remove:

如何删除:

rm -f 'find . | xargs grep -l email@domain.com'

0  

rm -f `find . | xargs grep -li email@domain.com`

does the job better. Use `...` to run the command to offer the file names containing email.@domain.com (grep -l lists them, -i ignores case) to remove them with rm (-f forcibly / -i interactively).

更好的发挥作用。使用“…“运行命令，提供包含电子邮件。@domain.com (grep -l列出它们，我忽略大小写)的文件名，并使用rm (-f force / -i交互性地删除它们)删除它们。”

I liked Martin Beckett's solution but found that file names with spaces could trip it up (like who uses spaces in file names, pfft :D). Also I wanted to review what was matched so I move the matched files to a local folder instead of just deleting them with the 'rm' command:

我喜欢Martin Beckett的解决方案，但发现有空格的文件名可能会出错(比如谁在文件名中使用空格，pfft:D)。我还想回顾一下匹配的内容，所以我将匹配的文件移动到一个本地文件夹，而不是用“rm”命令删除它们:

# Make a folder in the current directory to put the matched files
$ mkdir -p './matched-files'

# Create a script to move files that match the grep
# NOTE: Remove "-name '*.txt'" to allow all file extensions to be searched.
# NOTE: Edit the grep argument 'something' to what you want to search for.

$ find . -name '*.txt' -print0 | xargs -0 grep -al 'something' | awk -F '\n' '{ print "mv \""$0"\" ./matched-files" }' > doit.sh

Or because its possible (in Linux, idk about other OS's) to have newlines in a file name you can use this longer, untested if works better (who puts newlines in filenames? pfft :D), version:

$ find . -name '*.txt' -print0 | xargs -0 grep -alZ 'something' | awk -F '\0' '{ for (x=1; x doit.sh

# Evaluate the file following the 'source' command as a list of commands executed in the current context:
$ source doit.sh

NOTE: I had issues where grep could not match inside files that had utf-16 encoding. See here for a workaround. In case that website disappears what you do is use grep's -a flag which makes grep treat files as text and use a regex pattern that matches any first-byte in each extended character. For example to match Entité do this:

注意:在具有utf-16编码的文件中，我遇到了grep无法匹配的问题。请看这里的变通方法。如果这个网站消失了，你要做的就是使用grep -a标志，使grep将文件当作文本，并使用regex模式来匹配每个扩展字符中的任何第一个字节。例如，要匹配Entite，请这样做:

grep -a 'Entit.e'

and if that doesn't work then try this:

如果没有效果，试试这个:

grep -a 'E.n.t.i.t.e'
