There are a few things we could do to speed up processing 690,000 files, but we need a few more details to come up with something that stands a chance of working correctly and reasonably quickly. (Nothing reading 690,000 files is going to be quick, but there may be a difference between slow and SSSSLLLLLOOOOWWWW.)
Do any of the filenames you need to move contain any of the characters, <space>, <tab>, <newline>, <single-quote>, or <double-quote>? If so, which of these characters might appear in your filenames? If some of these characters do appear in your filenames, do they appear in all of your filenames? If not, how many of your filenames (that will be moved) will contain any of these characters?
Are all of the files you need to evaluate:
in a single directory?
in a single directory hierarchy?
in several single directories?
in several directory hierarchies?
If they are in single directories, do any of those directories contain any subdirectories?
Are all of the selected files going to a single directory? Or, if the files are coming from a directory hierarchy, is the hierarchy to be copied to the destination directory?
What is the minimum size, maximum size, and approximate average size (in bytes) of the files you need to evaluate?
Is it really true that all that needs to be checked is that there are three or more hyphens on the 3rd line of a file, or do we need to verify that the line starts with a [, ends with a ], and contains at least three hyphens surrounded by one of more lowercase letters?
Out of the 690,000 files you need to process; how many do you expect will be moved?
This User Gave Thanks to Don Cragun For This Post:
I am so so sorry for the late reply guys. I lost the file and it took me quite awhile to retrieve those back as the internet is slow here.
So,
Here's the info of the file size : 2,590,008,989 bytes (3.69 GB on disk) for 696,545 items
I believe each of the file size varies from 6kb to 18kb
And I am definitely sure all of the files are in single directory cause I am the one who created this mess =x
Some of the files doesn't contain hyphens at the 3rd lines at all. Especially those which file names are more than one word.
As it's all in single directory, it's hard for me to access them without terminal. So I wish to organize them by moving them into folders like 0H, 1H, 2H, 3H, 4H and so on. (H stands for hyphen btw )
Here's a sample of a file content that contains Hyphen at 3rd line

I didn't try the one-by-one command method as there is too many, however, I'd tried : awk 'FNR==3 && 1<gsub ("-", "&") {printf "%s%c", FILENAME, "\000"}' file* | xargs -I {X} -0 mv {X} ./new_directory
