I think that answers like this:

<pre><code>grep 'string1.*string2\|string2.*string1' filename

only match the case where both are present, not one or the other or both.

To search for files containing all the words in any order anywhere:

<pre><code>grep -ril \'action\' | xargs grep -il \'model\' | xargs grep -il \'view_type\'

The first grep kicks off a recursive search (<code>r</code>), ignoring case (<code>i</code>) and listing (printing out) the name of the files that are matching (<code>l</code>) for one term (<code>'action'</code> with the single quotes) occurring anywhere in the file.

The subsequent greps search for the other terms, retaining case insensitivity and listing out the matching files.

The final list of files that you will get will the ones that contain these terms, in any order anywhere in the file.

which has the advantage of working with overlapping strings. It's somewhat more straightforward using <code>perl</code> as <code>grep</code>, because you can specify the and logic more directly:

Don't try to use grep for this, use awk instead. To match 2 regexps R1 and R2 in grep you'd think it would be:

<pre><code>grep 'R1.*R2|R2.*R1'
</code></pre>

while in awk it'd be:

<pre><code>awk '/R1/ &amp;&amp; /R2/'
</code></pre>

but what if <code>R2</code> overlaps with or is a subset of <code>R1</code>? That grep command simply would not work while the awk command would. Lets say you want to find lines that contain <code>the</code> and <code>heat</code>:

<pre><code>$ echo 'theatre' | grep 'the.*heat|heat.*the'
$ echo 'theatre' | awk '/the/ &amp;&amp; /heat/'
theatre
</code></pre>

You'd have to use 2 greps and a pipe for that:

<pre><code>$ echo 'theatre' | grep 'the' | grep 'heat'
theatre
</code></pre>

and of course if you had actually required them to be separate you can always write in awk the same regexp as you used in grep and there are alternative awk solutions that don't involve repeating the regexps in every possible sequence.

Putting that aside, what if you wanted to extend your solution to match 3 regexps R1, R2, and R3. In grep that'd be one of these poor choices:

<pre><code>grep 'R1.*R2.*R3|R1.*R3.*R2|R2.*R1.*R3|R2.*R3.*R1|R3.*R1.*R2|R3.*R2.*R1' file
grep R1 file | grep R2 | grep R3
</code></pre>

while in awk it'd be the concise, obvious, simple, efficient:

<pre><code>awk '/R1/ &amp;&amp; /R2/ &amp;&amp; /R3/'
</code></pre>

Now, what if you actually wanted to match literal strings S1 and S2 instead of regexps R1 and R2? You simply can't do that in one call to grep, you have to either write code to escape all RE metachars before calling grep:

<pre><code>S1=$(sed 's/[^^]/[&amp;]/g; s/\^/\\^/g' &lt;&lt;&lt; 'R1')
S2=$(sed 's/[^^]/[&amp;]/g; s/\^/\\^/g' &lt;&lt;&lt; 'R2')
grep 'S1.*S2|S2.*S1'
</code></pre>

or again use 2 greps and a pipe:

<pre><code>grep -F 'S1' file | grep -F 'S2'
</code></pre>

which again are poor choices whereas with awk you simply use a string operator instead of regexp operator:

<pre><code>awk 'index($0,S1) &amp;&amp; index($0.S2)'
</code></pre>

Now, what if you wanted to match 2 regexps in a paragraph rather than a line? Can't be done in grep, trivial in awk:

<pre><code>awk -v RS='' '/R1/ &amp;&amp; /R2/'
</code></pre>

How about across a whole file? Again can't be done in grep and trivial in awk (this time I'm using GNU awk for multi-char RS for conciseness but it's not much more code in any awk or you can pick a control-char you know won't be in the input for the RS to do the same):

<pre><code>awk -v RS='^$' '/R1/ &amp;&amp; /R2/'
</code></pre>

So - if you want to find multiple regexps or strings in a line or paragraph or file then don't use grep, use awk.

Let's say we need to find count of multiple words in a file testfile.
There are two ways to go about it

1) Use grep command with regex matching pattern 

<pre><code>grep -c '\&lt;$DOG\|CAT$\&gt;' testfile
</code></pre>

2) Use egrep command 

<pre><code>egrep -c 'DOG|CAT' testfile 
</code></pre>

With egrep you need not to worry about expression and just separate words by a pipe separator.

<h3><a href="https://git-scm.com/docs/git-grep" rel="nofollow noreferrer"><code>git grep</code></a></h3>
Here is the syntax using <a href="https://git-scm.com/docs/git-grep" rel="nofollow noreferrer"><code>git grep</code></a> with multiple patterns:
<pre><code>git grep --all-match --no-index -l -e string1 -e string2 -e string3 file
</code></pre>
You may also combine patterns with Boolean expressions such as <code>--and</code>, <code>--or</code> and <code>--not</code>.
Check <code>man git-grep</code> for help.
<hr />
<blockquote>
<code>--all-match</code> When giving multiple pattern expressions, this flag is specified to limit the match to files that have lines to match all of them.
<code>--no-index</code> Search files in the current directory that is not managed by Git.
<code>-l</code>/<code>--files-with-matches</code>/<code>--name-only</code> Show only the names of files.
<code>-e</code> The next parameter is the pattern. Default is to use basic regexp.
</blockquote>
Other params to consider:
<blockquote>
<code>--threads</code> Number of grep worker threads to use.
<code>-q</code>/<code>--quiet</code>/<code>--silent</code> Do not output matched lines; exit with status 0 when there is a match.
</blockquote>
To change the pattern type, you may also use <code>-G</code>/<code>--basic-regexp</code> (default), <code>-F</code>/<code>--fixed-strings</code>, <code>-E</code>/<code>--extended-regexp</code>, <code>-P</code>/<code>--perl-regexp</code>, <code>-f file</code>, and other.

cat tst.txt |tr -d '\n' |grep "test1.*test3\|test3.*test1"

we just need to remove the newline character and it works!

Usage:

<pre><code>echo "a b c" | m -p A 
echo "a b c" | m -i -p A # a b c

You can put it in .bashrc if you like.

When the both strings are in sequence then put a pattern in between on <code>grep</code> command:

<pre class="lang-sh prettyprint-override"><code>$ grep -E "string1(?.*)string2" file
</code></pre>

Example if the following lines are contained in a file named <code>Dockerfile</code>:

<pre><code>FROM python:3.8 as build-python
FROM python:3.8-slim
</code></pre>

To get the line that contains the strings: <code>FROM python</code> and <code>as build-python</code> then use:

<pre class="lang-sh prettyprint-override"><code>$ grep -E "FROM python:(?.*) as build-python" Dockerfile
</code></pre>

Then the output will show only the line that contain both strings:

<pre class="lang-sh prettyprint-override"><code>FROM python:3.8 as build-python
</code></pre>

If git is initialized and added to the branch then it is better to use git grep because it is super fast and it will search inside the whole directory.

<pre><code>git grep 'string1.*string2.*string3'
</code></pre>

I am trying to use <code>grep</code> to match lines that contain two different strings. I have tried the following but this matches lines that contain either string1 or string2 which not what I want.

<pre><code>grep 'string1\|string2' filename
</code></pre>

So how do I match with <code>grep</code> only the lines that contain both strings?

Match two strings in one line with grep

我尝试使用grep来匹配包含两个不同字符串的行。我尝试了以下方法，但这匹配包含string1 或 string2的行，这不是我想要的。grep 'string1\|string2' filename那么，如何仅使用grep匹配包含这两个字符串的行呢
