32. Modify HP Unix kernel parameters

38. Empty the wtmps and btmps files with the following command

cat /dev/null > /var/adm/wtmps

cat /dev/null > /var/adm/btmps

39. last -R| more #Show previous successful login messages

lastb -R #Display information about previous failed logins

40. [zmosdbs->root:/infra/OS/WORK]# ./ kmeminfo #View memory info

41. export TMOUT=0 #Don't let shell session exit automatically

42. nwmgr #Network interface management command, check whether to configure APA dual network card binding

43. CM-->df -all -nc #Collect MP information

44. The nohup command and its output file

The nohup command: If you are running a process and you think it will not end when you exit your account, use the nohup command. This command allows you to continue running the process after you log out of the account/close the terminal. Nohup means no hang up.

The general form of this command is: nohup command &

Submit jobs using the nohup command

If you submit a job using the nohup command, all output from the job is redirected by default to a file named nohup.out, unless you specify an output file:

nohup command > myout.file 2>&1 &

45. Move to the specified directory according to time

# find . -mtime +90 -exec mv {} /var/tmp/date_90 \;

find . -mtime +365 -type f -name "*.trc" -exec rm -f {} \;

Retain nearly 600 days of data

46. file [filename] Tests the specified file, trying to guess the file type and display it

47. HP-UX umount file system times device busy--four steps with fuser command:

1. Confirm that the mount has processes that need to be killed

#fuser -cu /mount_point

2. Send a SIGKILL signal to the process:

#fuser -ck /mount_point

3. Check to see if any more processes are accessing the mount

#fuser -c /mount_point

4. mount mount point

#umount /mount_point

48. cat /etc/passwd |grep -E 'root| maxi50'filter multiple sets of keywords

49. dd command interpretation

dd if=/dev/zero of=/dev/rdisk/disk29 bs=1024k count=1000 ---> Empty the device, write a 1024k file, write 1000 times

dd: copies a file in blocks of a specified size and performs specified transformations while copying.

Note: Multiply the number specified if it ends with: b=512;c=1;k=1024;w=2

Parameter Notes:

1. if= filename: Enter the filename, default to standard input. That is, specify the source file.

2. of= filename: output filename, default is standard output. That is, specify the destination file.

3. ibs=bytes: reads bytes bytes at a time, i.e. specifies a block size of bytes bytes.

obs=bytes: Output bytes bytes at a time, i.e. specify a block size of bytes bytes.

bs=bytes: Set the block size of read/output to bytes at the same time.

4. count=blocks: copies only blocks, the block size is equal to the number of bytes specified by ibs.

50. swremove uninstall patch pack

51. swinstall -s install patch pack

52. ln -s #Create soft link

network aspect command

1. nwmgr #Unified command for managing all HP-UX LAN interfaces and RDMA interfaces

nwmgr --get #Lists all LAN interfaces and RDMA interfaces in the system

nwmgr -S apa -I 2 -A all #View lan2 details

You can use the nwmgr command on LAN interfaces or RDMA interfaces to do the following:

- Display interface information

- Modify interface settings

- Reset the interface or its statistics

- Connectivity of diagnostic links

- Also create and set configuration information for components

- Delete or clear components

2. netstat -in #View Server IP information (similar to ifconfig, ifconfig requires a specified interface command, e.g. ifconfig lanX)

3. netstat -rn #Check if IP address binding is correct

4. lanscan #Check the underlying physical status of the host, whether UP,(note that this command cannot see the IP layer)

5. nslookup hostname #See if you can parse yourself

6. lanadmin #local area network administrator

Assuming the corresponding port is LAN2, check with the following command:

#lanadmin -g 2 | grep Status

Administration Status (value) = up(1)

Operation Status (value) = up(1)
