UNIX for Dummies Questions & Answers

hi all,

Newbie to Unix and AIX. So my apologies if this is in the wrong place, etc.

Working on box -

uname# uname -a
AIX appt 3 5 00C08AAF4C00

when i type man (some valid command)
it just returns me to the # prompt.

Its running on the KSH shell.

man was working but i was trying to install monitor-9.1.2 so i could get system stats. I have put the tar.gz file in a directory of its own, un tz, and un tar'd it. Changed the makefile cause the 3 locations requiried where all looking at locations usr/local/man /ucd and /bin. so changed these to /usr/man /ucd and /bin.

tried to make the file but getting error

=====================================================
make: 1254-004 The error code from the last command is 1.
make: 1254-005 Ignored error code 1 from last command.
make all

make: 1254-004 The error code from the last command is 1.


Stop.
make: 1254-004 The error code from the last command is 2.


Stop.

since then man hasnt worked also some current cron jobs i.e. errclear are now not function saying cannot exec shell.

Im quite worried that i've managed to kill something here. Any advice welcomed.

Again this is kinda several problems but i think they're all linked.

Thanks in advance for the help.

just to update this.

i tried changing my cron jobs by putting /bin/ksh in front of the commands to get them to run in ksh rather than sh which i believe is the default for cron jobs. But still erroring out.

Also within /bin i cannot see an entry for sh ?!?! have i managed to delete my sh shell ??

From a troubleshooting standpoint, if my shell (either one) were missing, I'd start checking errpt for disk problems and root's shell (grep root /etc/passwd) to make sure it's where I think it's supposed to be. I'd also try a find / -name sh -print to try and locate it.

I'd log in to another 5.3 server and check out where sh is located and how /bin and /usr/bin are set up. On my AIX 5.3 server, /bin and /usr/bin are symbolically linked. There are 830 files in my /bin directory for comparison.

You're able to log in so there's a shell somewhere. Check /etc/passwd for the location of your shell. Mine's in /bin/ksh and root's is in /usr/bin/ksh.

ok

errpt returns the following

IDENTIFIER TIMESTAMP T C RESOURCE_NAME DESCRIPTION
BFE4C025 1114105506 P H sysplanar0 UNDETERMINED ERROR

grep root /etc/passwd
root:!:0:0::/:/usr/bin/ksh

So root must be using ksh.

as for finding sh - no relevant directories are returned.
I've checked my /bin and there is no sh. I can see the symbolic link between /bin and /usr/bin.

Roots shell is ksh as is my logon's.

Its just wierd that there is no sh within /bin now and that my cron jobs are failing.

ive got a nasty feeling somehow i've rm'd sh or what i was trying to do with the monitor program and installing that has corrupted or removed sh.
in which case how am i going to reinstall a shell!!! lol sounds like a nightmare. can always rebuild the box worst case but would like to avoid that

Cheers for the help by the way

In looking at my AIX 5.3 box:

Code:

AIX:stctivprd01$ ls -li ksh sh
 6340 -r-xr-xr-x   4 bin      bin          243428 Mar 03 2005  ksh
 6340 -r-xr-xr-x   4 bin      bin          243428 Mar 03 2005  sh

I see that sh and ksh are linked. So from within /bin type:

Code:

# ln ksh sh

And that should take care of that.

I thought that was the solution then mate. but alas i get this

# ls ksh sh
ls: 0653-341 The file sh does not exist.
ksh
# ls -li ksh
178 -r-xr-xr-x 4 root system 237948 16 Sep 2004 ksh

i know this is probably a really stupid question but if they're linked then can i just copy ksh in the same /bin directory and rename it sh then ln the two files ?
