I need to count all the .txt files in the current folder. I tried ls | grep .txt but if my folder content is: a.txt btxt c.c it will select a.txt and btxt and I only want files that end with .txt. I tried various combinations of regexp but with no result.

Find may be better than in this case since it is designed for handling file names:
find . -maxdepth 0 -name '*.txt' | wc -l Buf if you are very cautious about possibly strange file names:
find . -maxdepth 0 -name '*.txt' -exec echo 1 \; | wc -l

For Grep, using the character '.' means: "any character"... so you'll need to escape the dot:
ls | grep -e "\.txt" edit in fact the -e option is not even necessary. this will do the trick:
ls | grep "\.txt"

If all you need is number of files with extension '.txt' in current directory only, then this will also help.
ls -l *.txt | wc -l
