some years of gnulinux, commands i have found easy to understand, yet still useful
find . -print | grep <somefile> find . -printf '$TY-%Tm-%Td %p\n' | grep 2020-12-29 stat /files/* | grep -A5 <somenameoffile> | awk 'xor(/File/,/Modify/)' > /tmp/dates sed -e 's/original/new/g' -i editfileinplace.txt grep 'one|two|three' -search multiple items (may want to add -i to ignore case)
edit .bashrc
alias hs="history"
function cd() { builtin cd "$@"
if [ -f README ]
then
cat README
fi }
Useful but less intuitive commands
To get file counts for all directories (say you want to know how bloated / lean a software project is)
du -a | cut -d/ -f2 | sort | uniq -c | sort -nr
