The question is as simple as the logic I have here.
Assuming that files should always contain your .png .txt suffix etc ...
While folders / directories take nothing but their plain name
The idea is to get these referenced names and set a type icon: if it is a directory, set a folder icon . Now, if it's a file with an extension, set a file icon .
Could someone please kindly show me how I can write a bash shell script in order to detect what's inside a directory: file and folder
Bash has a built-in test that may be what you are looking for.
In a terminal, in any folder, type:
for i in * ; do if [ -d "$i" ] ; then echo "diretório - $i" ; else echo " arquivo - $i" ; fi ; done
More details, see the "bash" manual.
I post here as a record for future reference
Detect files and directories / folders via header:
All:
file *
Folders:
file * | grep -i directory
Files:
file * | grep -i text
Detect only directories / folders using the ls command:
ls -alp1 | grep -i "^d" | awk '{print $7}'
ls -d */
.. and it is done with find tranzing subfolders:
find ./ -type d
For . files:
ls -alp1 | grep -i "^-" | awk '{print $7}'
Now detect symbolic links (shortcut):
ls -alp1 | grep -i "^l" | awk '{print $7}'
