# find /sys -name rfkill
/sys/devices/platform/asus-nb-wmi/rfkill
/sys/devices/virtual/misc/rfkill
/sys/class/misc/rfkill
/sys/class/rfkill
/sys/module/rfkill
# find /sys -maxdepth 2 -name rfkill
/sys/class/rfkill
/sys/module/rfkill
# find /sys -type d -name rfkill 
/sys/devices/platform/asus-nb-wmi/rfkill
/sys/devices/virtual/misc/rfkill
/sys/class/rfkill
/sys/module/rfkill
# find /sys -type f -name rfkill
# find /sys -type l -name rfkill 
/sys/class/misc/rfkill
# find /sys -name rfkill -perm 755
/sys/devices/platform/asus-nb-wmi/rfkill
/sys/devices/virtual/misc/rfkill
/sys/class/rfkill
/sys/module/rfkill
# find /sys -name rfkill -user root
/sys/devices/platform/asus-nb-wmi/rfkill
/sys/devices/virtual/misc/rfkill

2.3 - ctime, atime, mtime, cmin, amin, mmin

# find /etc -type m -ctime 0
# find /etc -type f -mtime 100

Les mêmes recherches peuvent être effectués sur

2 - Caractères spéciaux, combinaisons

2.2 - Noms

# find /sys -type l -iname RFkill
/sys/class/misc/rfkill
# find /sys -type l -name "rfkill?"
/sys/class/rfkill/rfkill2
/sys/class/rfkill/rfkill0

/sys/class/drm
/sys/class/drm/card0-LVDS-1
/sys/class/drm/version
/sys/class/drm/renderD128

Critères multiples :

# find /sys -name asus* -not -name *nb*
/sys/module/asus_wmi
/sys/module/video/holders/asus_wmi
/sys/module/rfkill/holders/asus_wmi
