Hi,
Is there a way to know all unix error codes and what they means.

thx

Take a look at the file;

/usr/include/sys/errno.h

All the important unix error codes listed with a small description of each.

Also have a look at the errno(2) manual page and the "ERRORS" section of the relevant system call manual page.

I.e. when you see an errno *number*, you use /usr/include/sys/errno.h to convert the number to the mnemonic name.

Then, in a general case, look up the mnemonic name in the errno(2) manual page.

If, besides the error number/name, also the relevant system call (for example "write") is mentioned, then you can look up the specific meaning for that system call in the "ERRORS" section of it's manual page, i.e. "man 2 system_call" (for example "man 2 write").
