These are pretty basic but for me they are very useful to look at in a rush moment. I hope they help you too:
Lets say you have list of tar files to extract in /usr/sap/put/data file:
At the target dir:
for i in `ls /usr/sap/put/|grep -v data`
do
tar -xvf $i
done
You can use any command within for loop:
SAPCAR -xvf /usr/sap/trans/$i
If you want to process every single line in a file:
pcheck: (params has list of parameters)
for i in `cat params`
do
cat initBWD.ora|grep $i >> params_out
for i in `cat params_out`
do
cat initBWD.ora|grep $i
done
PS: � (single quota) string comes out
` (tick) command result comes out.
Produce a CDLIST file with the contents of CDLABEL.ASC in several directories:
# for i in `ls /sapcd/dvd*/CDLABEL.ASC`
> do
> cat $i>>CDLIST
> done
Memory cleanup commands:
ipcs -a |grep sid
ipcrm -m (# next to m)
ipcrm -s (# next to s)
cleanipc 00 (system number) remove
slibclean
Exclude in grep:
cat filename|grep -v text >> file.out --> -v will exclude the text
Exclude multiple entries:
df �k |grep �v data|grep �v �:�
Using grep -v, tar every file under /usr/sap/put except data into nevalstarfile:
for i in `ls /usr/sap/put|grep -v data'
do
tar -cvf /usr/sap/trans/tmp/nevalstarfile $i
done
Create a file with timestamp:
cp -p neval neval`date +%Y%m%d`
ls
neval
neval20050812
Find command options:
find . -mtime +365 -exec ls -l {} \; --> Find files older than 365 days and lists them
find . -name "lcd*" -mtime +5 -exec ls -l {} \; --> Finds files starting with lcd and older than 5 days.
Vi Replace:
:1,$ s/oldvalue/newvalue/g
1: First line
$: all the way to the end
s: substitute
g: globber
Netstat:
netstat -rn --> shows the routing table
route add -host IP address of the host -gateway IP address of the router at local
(sapserv4's IP) (router's IP in the company)
netstat �a|findstr 5555(port number)
Printers:
lpstat -pprintername for example lpstat -pNJ12 --> Shows the job queue
lpstat -vprintername
enable printername
cancel jobnumber
Check AIX APARs:
instfix -ik IY63076
XTERM:
Xterm �bg mistyrose �sb �sl 5000 �display @d&@
