The uniq unix command does what you want, with the -c option.

cat yourlog | uniq -c will output

   1 everity: Warning   Missing argument 1 for Pxxer_rzxczt_v3::mast() /sdfdsfv/ddw/hdd/nddd/system/adsdn/codsds/pr_rt_v3.php 115/dadm/index.php/plasdasd/mast/

This will however make repeated lines that are not directly repeated after each other to be counted up on different lines.

For example the input:

foo
foo
bar
bar
foo
foo

will give the output:

2 foo
2 bar
2 foo

If you want the output to be

2 bar
4 foo

you would first have to sort the file, like this:

cat yourlog | sort | uniq -c
