Bash Function to print out the files and the lines that contain a needle

The following code will create a function in bash that accepts two parameters (1: the place to search in, 2: the value to search for).

You can place it in your ~/.bashrc file to have it available whenever you open a bash shell.

#1. Copy/paste the below lines in your .bashrc

#takes 2 parameters (1: the haystack to search in, 2: the needle)
# Will print out the files and the lines that contain the needle
xfind(){
  FIND_VAR="$2";
  STACK="$1";
  if [ -f "$STACK" ] || [ -d "$STACK" ]; then
    find "$STACK" \
      -exec grep --color "$FIND_VAR" -sl '{}' \; \
      -exec grep "$FIND_VAR" -s '{}' \;
  else
    echo "ERROR: No file or folder with the name '$STACK' exist";
  fi
}
#2. Run source ~/.bashrc -- to reload 

Usage examples:

xfind . "bar";
xfind /etc/ "conf";
