This is my first post so I am not sure how things go here. I'm sorry if I'm breaking the rule or something. Feel free to correct me about that
So as I was saying...
I'd been trying to grep this folder containing 900,000 txt files but seems no luck. I get either "No such file or directory" or "Argument list too long" error each time I tried.
Here is the 2 final commands I used (I'm trying to grab all lines containing "[" btw)
"
"
[I get too many "No such file or directory"]
"
"
[No errors for this but it didn't do what it suppose to, only got 1 file result in the end.]
If grep is really impossible to achieve this, I do not mind using "cat" to compile all txt into one and "grep" that one big chunk of txt file. I'd also tried that but I could never escaped from "No such file or directory" or "Argument list too long" error.
Hi
Sorry, yes it was suppose to be
. I tried with both
and
but still get the same error.
And yes I am trying to compile all the lines containing "[" into one txt file from 900,000.
I'd been trying to do it many ways but I always end up with "No such file or directory" or "Argument list too long" error Some txt file name contain special characters but I managed to convert all of them from ".html" to become ".txt" by using -exec . I was hoping that could do the same to this execution. But my coding knowledge is not that flexible
You're welcome. Careful with the "." and "grep.txt" . Maybe give it a file extension other than ".txt", otherwise it is also part of the find operation..

OS=`awk '{print int($3)}' < /etc/redhat-release`
instead of

I am not sure if using cat -n is the most efficient way to split a file into multiple files, one file per line in the source file.
I thought using cat -n would make it easy to process the file because it produces an output that numbers each line that I could then grep for with the regex "^ *$i".... (3 Replies)
