Since agrep seems not to be present in your system, have a look in this alternative based on sed and awk to apply grep with and operation from patterns read by a local file.
PS: Since you use osx i'm not sure if the awk version you have will support bellow usage.
awk can simulate grep with AND operation of multiple patterns in this usage:
awk '/pattern1/ && /pattern2/ && /pattern3/'
So you could transform your pattern file from this:
$ cat ./tmp/d1.txt
"surveillance data" "surveillance technology" "cctv camera"
"social media" "surveillance techniques" "enforcement agencies"
"social control" "surveillance camera" "social security"
"surveillance data" "security guards" "social networking"
"surveillance mechanisms" "cctv surveillance" "contemporary surveillance"
To this:
$ sed 's/" "/\/ \&\& \//g; s/^"/\//g; s/"$/\//g' ./tmp/d1.txt
/surveillance data/ && /surveillance technology/ && /cctv camera/
/social media/ && /surveillance techniques/ && /enforcement agencies/
/social control/ && /surveillance camera/ && /social security/
/surveillance data/ && /security guards/ && /social networking/
/surveillance mechanisms/ && /cctv surveillance/ && /contemporary surveillance/
PS: You can redirect the output to another file by using >anotherfile in the end , or you can use the sed -i option to make in-place changes in the same search terms pattern file.
Then you just need to feed awk with awk-formatted patterns from this pattern file :
$ while IFS= read -r line;do awk "$line" *.txt;done<./tmp/d1.txt #d1.txt = my test pattern file
You could also not transform patterns in your original pattern file by applying sed in each line of this original pattern file like this:
while IFS= read -r line;do
line=$(sed 's/" "/\/ \&\& \//g; s/^"/\//g; s/"$/\//g' <<<"$line")
awk "$line" *.txt
done <./tmp/d1.txt
Or as one-liner:
$ while IFS= read -r line;do line=$(sed 's/" "/\/ \&\& \//g; s/^"/\//g; s/"$/\//g' <<<"$line"); awk "$line" *.txt;done <./tmp/d1.txt
Above commands return the correct AND results in my test files that look like this:
$ cat d2.txt
This guys over there have the required surveillance technology to do the job.
The other guys not only have efficient surveillance technology, but they also gather surveillance data by one cctv camera.
$ cat d3.txt
All surveillance data are locked.
All surveillance data are locked and guarded by security guards.
There are several surveillance mechanisms (i.e cctv surveillance, contemporary surveillance, etv)
Results:
$ while IFS= read -r line;do awk "$line" *.txt;done<./tmp/d1.txt
#or while IFS= read -r line;do line=$(sed 's/" "/\/ \&\& \//g; s/^"/\//g; s/"$/\//g' <<<"$line"); awk "$line" *.txt;done <./tmp/d1.txt
The other guys not only have efficient surveillance technology, but they also gather surveillance data by one cctv camera.

Update:
Above awk solution prints the contents of matching txt files.
If you want to display the filenames instead of the contents, then use the following awk where necessary:
awk "$line""{print FILENAME}" *.txt

ls -R *.pdfwould invokelsrecursively on anything matching*.pdf(if there's nothing matching*.pdfin the current directory, you'll get no result, and if there is, it will only recurse into it if it's a directory).ls -R | grep pdfwould show you everything in thels -Rresult that matches the regular expressionpdf, which is not what you want.This is what you need:
This will give you the pathnames of all regular files (
-type f) in or below themyfolderdirectory whose filenames matches the pattern*.pdf. The pattern needs to be quoted to protect it from the shell.With the
zshshell (which recently became the default shell on macOS):This would print out the pathnames of all regular files in or below the directory
myfolderthat have names ending in.pdf, in a single column. The matching would include hidden names. TheNandDin the glob qualifier corresponds to setting thenullglobanddotglobshell options in thebashshell (but only for this single globbing pattern), and the dot makes the pattern only match regular files (i.e. not directories etc.)
