Count the number of files in a directory containing two specific string in bash - bash

Question

I have few files in a directory containing below pattern:
Simulator tool completed simulation at 20:07:18 on 09/28/18.
The situation of the simulation: STATUS PASSED
Now I want to count the number of files which contains both of strings completed simulation & STATUS PASSED anywhere in the file.
This command is working to search for one string STATUS PASSED and count file numbers:
find /directory_path/*.txt -type f -exec grep -l "STATUS PASSED" {} + | wc -l
Sed is also giving 0 as a result:
find /directory_path/*.txt -type f -exec sed -e '/STATUS PASSED/!d' -e '/completed simulation/!d' {} + | wc -l
Any help/suggestion will be much appriciated!

Answer 1

find . -type f -exec \
awk '/completed simulation/{x=1} /STATUS PASSED/{y=1} END{if (x&&y) print FILENAME}' {} \; |
wc -l
I'm printing the matching file names in case that's useful in some other context but piping that to wc will fail if the file names contain newlines - if that's the case just print 1 or anything else from awk.
Since find /directory_path/*.txt -type f is the same as just ls /directory_path/*.txt if all of the ".txt"s are files, though, it sounds like all you actually need is (using GNU awk for nextfile):
awk '
FNR==1 { x=y=0 }
/completed simulation/ { x=1 }
/STATUS PASSED/ { y=1 }
x && y { cnt++; nextfile }
END { print cnt+0 }
' /directory_path/*.txt
or with any awk:
awk '
FNR==1 { x=y=f=0 }
/completed simulation/ { x=1 }
/STATUS PASSED/ { y=1 }
x && y && !f { cnt++; f=1 }
END { print cnt+0 }
' /directory_path/*.txt
Those will work no matter what characters are in your file names.

Answer 2

Using grep and standard utils:
{ grep -Hm1 'completed simulation' /directory_path/*.txt;
grep -Hm1 'STATUS PASSED' /directory_path/*.txt ; } |
sort | uniq -d | wc -l
grep -m1 stops when it finds the first match. This saves time if it's a big file. If the list of matches is large, sort -t: -k1 would be better than sort.

Answer 3

The command find /directory_path/*.txt just lists all txt files in /directory_path/ not including subdirectories of /directory_path
find . -name \*.txt -print0 |
while read -d $'\0' file; do
grep -Fq 'completed simulation' "$file" &&
grep -Fq 'STATUS PASSED' "$_" &&
echo "$_"
done |
wc -l
If you ensure no special characters in the filenames
find . -name \*.txt |
while read file; do
grep -Fq 'completed simulation' "$file" &&
grep -Fq 'STATUS PASSED' "$file" &&
echo "$file"
done |
wc -l
I don't have AIX to test it, but it should be POSIX compliant.
