How can I set different permissions for files and folders separately?

Solution 1:

Use find:

find ./ -type f -maxdepth 1 -exec chmod 644 {} \;
find ./ -type d -maxdepth 1 -exec chmod 755 {} \;

-type f: Files
-type d: Directories
-maxdepth 1: first level (to avoid default recursive behavior)
-exec: execute command on with argument from result
{} will be replaced with a line from results. try:
```
find ./ -type d -maxdepth 1 -exec echo hi{}low \;
```
This useful for commands which have different arguments order like ln:
```
ln -s {} ./otherfolder/{}
```
or cp
```
cp {} ./otherfolder/
```
\; to to tell -exec is the end of command because you can add other find options after -exec (so they will not mix up). try:
```
find ./ -type d -maxdepth 1 -exec echo
```
