counting a list of string in a list of txt files
Hi there!
I have 150 txt files named chunk1, chunk2, ........., chunk150. I have a second file called string.txt with more than 1000 unique strings, house, dog, cat ... I want to know which command I should use to count how many times each string appears in the 150 files.
I have tried with a grep -c dog chunk* but then I get the count of all of the files and I have to do it separately for each of the strings.
The ideal solution would be an output saying:
dog 45
cat 69
house 92
song 45
Thanks a lot in advance.
Kind regards,
Pep

Hi,
I have a list of zipped files. I want to grep for a string in all files and get a list of file names that contain the string. But without unzipping them before that, more like using something like gzcat.

NAME
PCRE - Perl-compatible regular expressions
PCRE SAMPLE PROGRAM
A simple, complete demonstration program, to get you started with using PCRE, is supplied in the file pcredemo.c in the PCRE distribution.
A listing of this program is given in the pcredemo documentation. If you do not have a copy of the PCRE distribution, you can save this
listing to re-create pcredemo.c.
The program compiles the regular expression that is its first argument, and matches it against the subject string in its second argument.
No PCRE options are set, and default character tables are used. If matching succeeds, the program outputs the portion of the subject that
matched, together with the contents of any captured substrings.
If the -g option is given on the command line, the program then goes on to check for further matches of the same regular expression in the
same subject string. The logic is a little bit tricky because of the possibility of matching an empty string. Comments in the code explain
what is going on.
If PCRE is installed in the standard include and library directories for your operating system, you should be able to compile the demon-
stration program using this command:
gcc -o pcredemo pcredemo.c -lpcre
If PCRE is installed elsewhere, you may need to add additional options to the command line. For example, on a Unix-like system that has
PCRE installed in /usr/local, you can compile the demonstration program using a command like this:
gcc -o pcredemo -I/usr/local/include pcredemo.c
-L/usr/local/lib -lpcre
In a Windows environment, if you want to statically link the program against a non-dll pcre.a file, you must uncomment the line that
defines PCRE_STATIC before including pcre.h, because otherwise the pcre_malloc() and pcre_free() exported functions will be declared
__declspec(dllimport), with unwanted results.
Once you have compiled and linked the demonstration program, you can run simple tests like this:
./pcredemo 'cat|dog' 'the cat sat on the mat'
./pcredemo -g 'cat|dog' 'the dog sat on the cat'
Note that there is a much more comprehensive test program, called pcretest, which supports many more facilities for testing regular expres-
sions and the PCRE library. The pcredemo program is provided as a simple coding example.
If you try to run pcredemo when PCRE is not installed in the standard library directory, you may get an error like this on some operating
systems (e.g. Solaris):
ld.so.1: a.out: fatal: libpcre.so.0: open failed: No such file or directory
This is caused by the way shared library support works on those systems. You need to add
-R/usr/local/lib
(for example) to the compile command to get round this problem.
