Re: Possible to reset Linux file permissions w/in webcat [shell] ?

texte = WebCat runs under Linux as a non-priveledged user, so there are lots of things that you cannot do directly using [SHELL]. It is, however, possible to use a SUID script to do the file permission/ownership changes. Have your sys admin create a script to chmod/chown the files, then flag it as SUID: chmod +s scriptnameI would recommend that the script should not accept any command line parameters; it is too dangerous. SUID script's run with the rights of the file's owner, not the user running the script. Hence you could have a script owned by root, that an unprivileged user could run.I have not written one yet (mostly because I AM the sysadmin), but the best design would be to have a directory structure parallel to the production files. So if your production files are in /home/http/htdocs/site1/...you should have a directory /home/youruser/htdocs/site/...and the script would copy the files to their real home, change the rights and ownership. I would recommend a script that simply copies all files from the current directory to the matching directory in the live system. Then you could move the script around to wherever you wanted to; there is no real reason to do this via WebCat at all.hope this gives you some ideas...John PeacockJohn Butler wrote: > > Linux , WC 3.08 > > Is it possible to reset file permissions within a webcat [shell] context?
