Multiple commands are available for finding files:
find command (most powerful):
# Find by name
find /path -name "filename"
find . -name "*.txt"
# Find by type
find /home -type f # Files only
find /home -type d # Directories only
# Find by size
find /var -size +100M # Files larger than 100MB
find . -size -1k # Files smaller than 1KB
# Find by permissions
find . -perm 755
find . -perm -u+x # Files executable by owner
# Find and execute action
find /tmp -name "*.tmp" -delete
find . -name "*.log" -exec rm {} \;
locate command (faster, uses database):
locate filename
updatedb # Update locate database
which/whereis commands:
which python # Find executable in PATH
whereis python # Find binary, source, manual
