Installing PHP on Linux (CentOS release 6.4 Final)

Mount the DVD go to the Packages directory and install the packages manually with rpm command.
You can do this task with yum too, for that you will have to setup YUM repository.

Useful One liners.

Excellent example of appending the "/home/" in front of all the users name in a file
which has 3222 records.


%s/^/\/home\//g


----------------------------------------------


 df -hl | awk '{ print $1 "; " "\t" $5}' | sort -n

------------------------------------------

AUTOENV=/opt/CA/WorkloadAutomationAE/autouser.PRD/autosys.sh.trs20

--------------------------------------------

Following command will create 1 GB File system

dd if=/dev/zero of=test.iso2 bs=1024 count=1000000

--------------------------------------------


Following command will count the file size in GB/MB i.e. in human readable form:

for i in `du -sh * |sort -n |cut -f2`; do du -sh $i; done

--------------------------------------------

# tar -xvf etc.tar -C test/  ---> Untar the tarball in test directory.

# tar -tvf etc.tar ---> To view the tarball contents without actually extracting.

--------------------------------------------

Use dd command to create an ISO image

# if=/dev/cdrom of=/datacdimg.iso

thats it!

--------------------------------------------

# cut -d: '' -f1 passwd ---> Will print first column

# cut -d: -f1,6 passwd ---> will extract user &  home directory.

--------------------------------------------
awk:bash

awk -F':' '{print $1}' passwd  ---> This will get the first column separated by : ex. passwd file.
