I need to get all file names, not including the paths eg file1 is correct and ./folder/file1 is incorrect, from subdirectories. My use case is retrieving all available terminfo file names which are located inside /usr/share/terminfo directory. But they are located inside another set of subdirectories as follows -

terminfo ア ls
1  3  5  7  9  A  c  e  f  h  j  l  m  n  o  P  Q  s  u  w  X
2  4  6  8  a  b  d  E  g  i  k  L  M  N  p  q  r  t  v  x  z

terminfo ア cd 1
1 ア ls
1178  1730-lm

You can see files are located inside these 1 3 or A subdirectories and I need all file names from each subdirectories. There are a total of 42 directories, 2720 files so manual process would be exhausting.

find /usr/share/terminfo -type f -exec basename {} \;

  • find /usr/share/terminfo -type f -exec basename {} \; | wc -l gives 2718 while tree reports 42 directories, 2720 files.. Feb 18 '17 at 9:38
  • @AbhinavGauniyal I can't reproduce that discrepancy.

  • [usr@server terminfo]$ tree | tail -n 1 21 directories, 119 files [usr@server terminfo]$ find /usr/share/terminfo -type f -exec basename {} \; | wc -l 119

Since we know that the files we'd like to have the names of are two levels under /usr/share/terminfo, and that there are no further directories beneath that, this would be a fast solution (only executes find and cut once):

$ find /usr/share/terminfo -type f | cut -d '/' -f 6

Alternatively, with one slightly "heavier" sed substitution:

$ find /usr/share/terminfo -type f | sed 's#^.*/##'

The sed substitution removes everything up to and including the last / of each line of output from find.

1 Using tree

(man tree for details)

tree -i /usr/shar/terminfo

or if you want do remove the directories:

tree -iF /usr/shar/terminfo | grep -v /

2 Using ls

ls -R /usr/share/terminfo  | grep -v /
ls /usr/share/terminfo/*/* | grep -o '[^/]*$'

basename -a $(ls /usr/share/terminfo/*/*)
