This should be a task for <code>awk</code>, could you please try following written and tested with shown samples in GNU <code>awk</code>.
<pre><code>awk '
FNR==NR{
 arr[$0]=FNR
 next
}
FILENAME==&quot;fileC.txt&quot;{
 arrVal[++count]=$0
 next
}
FILENAME==&quot;fileB.txt&quot;{
 for(key in arr){
 if(sub(key,arrVal[arr[key]])){
 break
 }
 }
 print
}
' fileA.txt fileC.txt fileB.txt
</code></pre>
Output will be as follows.
<pre><code>4472534
866FF72
3511GYT
333553D
8645141

</code></pre>
Explanation: Adding detailed explanation for above.
<pre><code>awk ' ##Starting awk program from here.
FNR==NR{ ##Checking condition which will be TRUE when fileA.txt is being read.
 arr[$0]=FNR ##Creating arr with index of current line and value of current line number.
 next ##next will skip all further statements from here.
}
FILENAME==&quot;fileC.txt&quot;{ ##Checking condition if file name is fileC.txt then do following.
 arrVal[++count]=$0 ##Creating arrVal with index of count increasing value of 1 and having current line as its value.
 next ##next will skip all further statements from here.
}
FILENAME==&quot;fileB.txt&quot;{ ##Checking condition if file name is fileB.txt then do
 for(key in arr){ ##Traversing through array arr here.
 if(sub(key,arrVal[arr[key]])){ ##Checking condition if substitution of arrVal[arr[key]] is successfully done with key in current line, which basically changes the values in fileB values.
 break ##Come out of loop to save some cycles.
 }
 }
 print ##Printing current line here.
}
' fileA.txt fileC.txt fileB.txt ##Mentioning Input_file names here.
</code></pre>
NOTE: We could also use <code>ARGC</code> conditions check in place of file name checks too in above.

blocks|key|1304349|text|您可以使用sed生成一个可以替换它们的sed脚本：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1304350|sed+"$(paste+fileA.txt+fileC.txt+%7C+sed+'s/$.*$\t$.*$/s@\1@\2@g/')"+fileB.txt|code-block|syntax|javascript|1304351|entityMap^0|5|3|J|3|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|L|$]]

You could use <code>sed</code> to generate a <code>sed</code> script that would replace them:
<pre><code>sed &quot;$(paste fileA.txt fileC.txt | sed 's/$.*$\t$.*$/s@\1@\2@g/')&quot; fileB.txt

Here is a one liner with <code>paste + awk + sed</code>:

blocks|key|2694354|text|这可能适用于您(GNU和并行)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2694355|parallel+echo+'s/{1}/{2}/'+::::%2B+file[AC]+%7C+sed+-f+-+fileB|code-block|syntax|javascript|2694356|构建一个sed脚本，然后以fileB作为输入运行脚本。|2694357|注：::::%2B模拟粘贴命令，{1}和{2}模拟fileA和fileC中每一行的值。|offset|length|style|CODE|2694358|entityMap^0|0|0|0|2|5|E|3|I|3|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|T|8|@$K|U|L|V|M|N]|$K|W|L|X|M|N]|$K|Y|L|Z|M|N]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|10|8|@]|9|@]|A|$]]]|P|$]]

This might work for you (GNU sed &amp; parallel):
<pre><code>parallel echo 's/{1}/{2}/' ::::+ file[AC] | sed -f - fileB
</code></pre>
Build a sed script and then run the script with fileB as input.
N.B. <code>::::+</code> emulates the paste command and <code>{1}</code> and <code>{2}</code> the values of each line from fileA and fileC.

I have a file of patterns (fileA.txt) which need to be searched in a large file (fileB.txt) and they need to be replaced with patterns in another file (fileC.txt)
Example:
<pre><code>fileB.txt
4472534
8BC4232
3533221
333553D
8645141
2412AAA
</code></pre>
I want to search this patterns in fileB:
<pre><code>fileA.txt
BC423
33221
12AAA
</code></pre>
Then I want to replace them with patterns in fileC, line by line:
<pre><code>fileC.txt
66FF7
11GYT
2HHJK
</code></pre>
Expected output:
<pre><code>4472534
866FF72
3511GYT
333553D
8645141
242HHJK
</code></pre>
I wrote something like this:
<pre><code>grep -f fileA.txt fileB.txt | xargs sed -i fileC.txt
</code></pre>
however, it searches correctly the patterns but the substitution is probably not correct.
Any advice?
<pre><code>fileA (pattern to search)
