1. deleting files

[Email protected] ~]# rm/tmp/allin/2/3/1.txt RM: Do you want to delete the plain empty file "/tmp/allin/2/3/1.txt"? Y[[email protected] ~]# tree/tmp/allin/tmp/allin├──1│└──2└──2└──34 directories, 0 files

• Delete a non-empty directory

[[email protected] ~]# rm /tmp/allin/2/3rm:  Unable to delete "/TMP/ALLIN/2/3":  is a directory [[email  protected] ~]# rm /tmp/allin/2/3/1.txt  2.txt  [[email protected ] ~]# rm /tmp/allin/2/3/1.txt  2.txt  [[email protected] ~]#  RM /TMP/ALLIN/2/3/*.TXTRM: Do you want to delete the normal empty file   "/tmp/allin/2/3/1.txt"? NRM: Do you want to delete the normal empty file   "/tmp/allin/2/3/2.txt"? N 

• Every time you ask for more files, it can be troublesome.   -f option is forced to delete without asking.

[Email protected] ~]# TREE/TMP/ALLIN//TMP/ALLIN/├──1│└──2└──2└──3├──1.TXT└──2.TXT4 Director IES, 2 files[[email protected] ~]# rm-f/tmp/allin/2/3/*.txt[[email protected] ~]# tree/tmp/allin//tmp/allin/├──1│└─ ─2└──2└──34 directories, 0 files

2. Deleting a directory

[[email protected] ~]# rm/tmp/allin/2/3/rm: Cannot delete '/tmp/allin/2/3/': is a directory

There will be an error. Because it is a non-empty directory.

• Requires     options

[[EMAIL PROTECTED] ~]# RM -R /TMP/ALLIN/2/3/RM: Do you want to delete the directory   "/tmp/allin/2/3/"? y[[email protected] ~]# !treetree /tmp/allin//tmp/allin/├── 1│   └──  2└── 23 directories, 0 files 

• Don't want to ask, plus -f options

[Email protected] ~]# rm-rf/tmp/allin/2[[email protected] ~]#!treetree/tmp/allin//tmp/allin/└──1└──22 Directori ES, 0 files

• Visualization, plus -v options

[[EMAIL PROTECTED] ~]# RM -RFV /TMP/ALLIN/1 deleted directory: "/TMP/ALLIN/1/2" deleted directory: "/TMP/ALLIN/1 "[[Email protected] ~]# ls /tmp/allin/[[email protected] ~]# !treetree  /tmp/allin//tmp/allin/0 directories, 0 files 

-f options are awesome, but be sure to use them with caution.

-fSome of the disadvantages of the options

• Delete the directory that does not exist, also will not error, easy to cause confusion.

[[email protected] ~]# tree/tmp/allin/tmp/allin0 directories, 0 files[[email protected] ~]# rm-f/TMP/ALLIN/2
