The version 5.3 which thread-owner showed is already out of support, but the following is true for the latest versions (7.1) either:

AIX uses a ksh88 as the default system shell (/bin/ksh), but comes with a ksh93 per default. One will have to use /bin/ksh93 to access it, though.

I hope this helps.


PS: sitting at my office keyboard now i am able to expand on that:

The basic system default shell is a ksh88 and its version string is: Version M-11/16/88f. This has not changed in ages and is true for probably all the AIX systems you will ever encounter, because i doubt you will have a chance to see a pre-3.2.5-system running somewhere.

The /bin/ksh93 produces the version string Version M 93t+ 2009-05-01 issued from a 7.1-system patched to the latest level. I cannot check on any 5.3-system (they are out of support and we do not have any), but IIRC the later releases of 5.3 used the same ksh93 version. 6.1 definitely does.

I hope this helps.

      tar all ".csv" files of both dir to ./05_backup/backup_ok_ko_currentDate(ddmmYYYY_hhmmss).tar
elseif "03_ok" or "04_ko" != empty then
   if "03_ok" != empty then
      tar all ".csv" files
      tar all .cvs to ./05_backup/backup_ok_currentDate(ddmmYYYY_hhmmss).tar
      tar all ".csv" files
      tar all .cvs to ./05_backup/backup_ko_currentDate(ddmmYYYY_hhmmss).tar
   end if
end if

clean dir "03_ok" and "04_ko" if != empty

read all ".cvs" files in a dir (not subdir), with, part of filename, containing adate in format "mmYYYY" (for the next month)
   for each file, call a (still unknow) script to copy it to another position
      if result of copy it's ok
         copy it to "03_ok" dir
         copy it to "o4_ko" dir
      end if

This is still confusing. "03_ok" and "04_ko" appear to be strings (and are clearly not empty strings). Are they the names of subdirectories in the current directory? Are they the names of variables that expand to absolute pathnames of directories? Are they the names of variables that expand to relative pathnames of directories?

What do you mean by != empty? Do you mean that the directory to which they refer does not contain any files other than . and .., does not contain any files with names ending in .csv, or something else (and, if so, what)?

What is another position to which files are to be copied?
You have references to *.csv and *.cvs. Are the references to *.cvs supposed to be *.csv, or do you really have files with both suffixes?

It sounds like you have a directory that contains some .csv (or .cvs or both) and you want to copy those files from one directory into a tar archive, then you want to try to copy those same files to another directory and then copy the same file to a third or fourth directory depending on whether the 2nd copy succeeded or failed. Do you really need four copies of each of these files (or were one or more of the copy it to statements intended to be move it to)?
