The -i option in sed allows in-place editing of the input file. Replace myexpression with any regular expression. /expr/d syntax means if the expression matches then delete the line. You can reverse the functionality to keep matching lines only by using:
sed -i -n '/myexpression/p' /path/to/file.txt11sed -i '/myexpression/d' /path/to/file.txt -

With this form you dont need to cut out target directory using grep/sed/etc.
4(ls; mkdir subdir; echo subdir) | xargs mv -
This is a cool trick to view the contents of the file on /dev/pts/0 (or whatever terminal you're using), and also send the contents of that file to another program by way of an unnamed pipe. All the while, you've not bothered saving any extra data to disk, like you might be tempted to do with sed or grep to filter output.
2cat /path/to/some/file.txt | tee /dev/pts/0 | wc -l -
