rsync.sh

# rsync dirs
# show progress (--progress) and update only newer (--update)
# cd into the target directory and run
rsync -avzh --progress --update ~/source-dir/ .

# to delete files on the target directory
rsync -avzh --progress --update --delete ~/source-dir/ .

# to exclude multiple patterns
rsync -avzh --progress --update --delete ---exclude '*.min.*' --exclude 'cache' --exclude 'uploads' ~/source-dir/ .

# to include only specific filetypes
rsync -avzh --progress --update --delete --include='**/' --include='*.jpg' --exclude='*' ~/source-dir/ .

# for timestamp diffs between source and destination
# use --modify-window=[amount-of-time-in-seconds]
# see https://wiki.glitchdata.com/index.php?title=Rsync:_Modify_Window
rsync -avzh --progress --update --modify-window=1 ~/source-dir/ .

# for utf-8 filename conversion issues (macos to linux)
# try the option --iconv=utf-8,utf-8 or --iconv=utf-8-mac,utf-8
# see https://serverfault.com/a/639367 and https://elliotli.blogspot.ch/2011/10/using-rsync-to-migrate-data-between.html

search.sh

# find in current and subdirs by name and ls -l the searchresults
find . -name "*Searchstring*" -exec ls -l {} \;

# find a string current and subdirs (-R) and list matching filenames (-l)
grep -Rl "Searchstring" ./

grep -Rn "Searchstring" ./

# find a string current and subdirs (-R) matching filepattern (--include=*.scss)
# and list matching filenames with context and line number (-n)
grep --include=*.scss -Rn "Searchstring" ./

# find string with variable-names prefixed with a dollar-sign like $variable-name and single-quotes to compare
# NOTE: you have to escape the dollar sign with three backslashes to prevent bash from using ENV variable --> "\\\$variable-name"
grep --include=*.scss -PRn "\\\$variable-name: '';"

# NOTE: for zsh you have to escape * in --include= otherwise it would throw "zsh: no matches found: --include=*.scss"
grep --include=\*.scss -PRn "\t[^\/]*\\\$variable-name: '';"

# looking for aria-hidden in themes/**/*.php
grep -Rion ".*aria-hidden.*" ./**/themes/**/*.php
