Bash: Find command to search multiple phrasses in each file?

Quote:

declare -a phrasses
phrasses[0]="phrasse 1"
phrasses[1]="phrasse 2 something'something\"something\" https://www.domain.com/');"
phrasses[2]="phrasse 3"

wheretosearch=/home
outputfile=/tmp/find_malicious_output.txt

for (( i=0;i<${#phrasses[*]};i++ )); do
phrasse=${phrasses[$i]}
echo "$phrasse"
find $wheretosearch -type f -size -800k -mmin -1440 -exec grep -l "$phrasse" {} \; >> $outputfile

Please how can i make this to search one file only once and all phrasses in it?
I mean i have around 30 phrasses and i dont want to do search 30 times, but only 1 time and search in file, you know to save io resources and time

So where are you stuck ? Also, make it clear, do you want to search some particular files or want to serach some keyword in the file content?
You can use -name option, instead of grep piped with find cmd, like:

Code:

find $wheretosearch -type f -size -800k -mmin -1440 -name "$phrasse" -print >> $outputfile

Don't forget to close for loop in your script with do-done.

And grep allows for alternatives... "phrase | phrase2 | phrase3"

Thank You,

so this is part of my find command:

Quote:

-exec grep -l "$phrasse" {} \; >> $outputfile

how i can make it so i can search for not one, but twenty phrasses and if any or several of them found in the file, it output into the file?

the search phrasses will contain example this:

url=<?php echo $rand_url;?>
http://www
\"ftp\"
\'ftp\'

:-O
