awk '{gsub(/"/,"",$7); print $7}' access.log

I've recently updated my php and found, that the settings for apache did not match the php cli version. I had to set the cli version with the following procedure:

Alle Zeilen mit # Am Anfang ergaenzen.

:%s@^@#&@

find -maxdepth 1 -type d -not -name "*hide*"

= Show all directories directly located in the current directory which do not have the word 'hide' in their name.

Useful to check where a script drops exactly and what's the output of variables, find, etc.:

sh -x ./scriptname

Change files or directories by appending a string (_2_DELETE) to their name:

mv filename{,_2_DELETE}

Useful and fast:

find -type f -name 'filename' -exec grep -H 'text to find' {} +

Same result and maybe even better performance:

For some years I had problems when updating or installing a site with composer from my vagrant box.
