Shell Programming and Scripting

ok, Is it possible to check UID and GID also ..(which i have marked) ?

any idea?

yes ofcourse
this will check for UID=root and GID=system

Code:

ls -l *.a|awk '{k=0;for(i=6;i<=8;i++)k+=((substr($1,i+2,1)~/[rwxs]/)*2^(8-i));if(k==7 && $3=="root" && $4=="system"){printf(" %0o ",k);print $9;}'

modify as you want

Code:

$ find /etc /bin /usr/bin /usr/sbin /var/adm \
-name '*.a' \
'!' '(' -user root -o -user daemon -o -user bin -o -user sys ')' \
'!' '(' system -o -group security -o -group bin -o -group sys ')' \
-ls | awk '$3~/[r-]-[x-]$/{print $11}'

Add additional users/groups as needed

Thank your help. but the problem with this script is .. For eg : If there is no *.a file found ,with Owner as System , it terminates the execution there itself and would not excute further. It shows an error message like " System user not found " ..

Please advise

find /etc /bin /usr/bin /usr/sbin /var/adm \ -name '*.a' \ '!' '(' -user root -o -user daemon -o -user bin -o -user sys -o -user adm -o -user uucp -o -user nuucp -o -user lpd -o -user imnadm -o -user ipsec -o -user ldap -o -user lp -o -user snapp -o -user invscout ')' \ '!' '(' -group system -o -group security -o -group bin -o -group sys -o -group adm -o -group uucp -o -group mail -o -group printq -o -group cron -o -group audit -o -group shutdown -o -group ecs -o -group imnadm -o -group ipsec -o -group ipsec -o -group ldap -o -group lp -o -group haemrm -o -group snapp -o -group hacmp')' \ -ls


ABove is the sequence of commands that I am trying to execute. The problem is , if the find command does not find any *.a file whose owner is one of the system userids which we have mentioned in the comamnd sequence above , then it stops execution with an error message( User does not exist) and does not get further.Ideally we want the command sequence above to dispaly those *.a files which are owned by general userids other than the system userids mentioned above.Is there any way of ignoring this error message to continue the execution till the end .?
