To remove the charachters “ < > : * | ? from filenames in the current folder (especially handy when files need to be placed on onedrive/windows share)

for f in *; do mv -i "$f" "${f//[\"<>:\*\|\/\?]}"; done

It's also possible to remove all spaces in filenames by including [:space:] in the string.

for f in *; do mv -i "$f" "${f//[\"<>:\*\|\/\?[:space:]]}"; done

parse_git_branch() {

}

export PS1="\n[\\D{%Y-%m-%d %H:%M.%S}] \[\033[01;34m\]\w\[\033[00m\]\n\[\033[33m\]\$(parse_git_branch)\[\033[00m\]\[\033[01;32m\][\u@\h]\[\033[00m\]: \$ "

For the root user maybe a red color for the username and server is better

export PS1="\n[\\D{%Y-%m-%d %H:%M.%S}] \[\033[01;34m\]\w\[\033[00m\]\n\[\033[33m\]\$(parse_git_branch)\[\033[00m\]\[\033[01;31m\][\u@\h]\[\033[00m\]: \$ "
