yael's questions

I need advice about the following

I build simple spec file and build rpm

I transfer the new rpm to other Linux machine in order to install the new rpm

according to the spec file the new rpm -> test.sh-6.2-2.i386.rpm should create the /tmp/MY_RPM_TESTS directory , but this rpm not create the MY_RPM_TESTS and sub directories please advice why , what I need to fix in the spec file?

RPM installation:

   [root@linux1 rpm -Uvh  /root/rpmbuild/RPMS/i386/test.sh-6.2-2.i386.rpm
   Preparing...                ########################################### [100%]

I have the following spec file (below), I want to add to the Source - /root/calculate.sh

How do I add second source ?

For example

Source: /root/test.sh /root/calculate.sh ( is illegal)

I build a simple rpm based on spec file but my target is after I installed the rpm by rpm -Uvh , is to put the test.sh file under /home directory, please advice what I need to change in the spec file in order to put the test.sh after I installed the rpm ?

remark: test.sh defined under /usr/src/redhat/SOURCES

 [root@linux /usr/src/redhat]# ls

please advice why I get the error "error: License field must be present in package: (main package)"

I need to create rpm file ,

I only have the spec file under SPECS

and the test.sh script under SOURCES

what’s wrong here?

 [root@linux /usr/src/redhat]# ls

I create some scripts under my Linux machine RedHat-Linux-OS-5.3

the following scripts home directory is /root/dir

And the scripts are:

/root/dir/rfg.sh
/root/dir/ener.pl
/root/dir/wnr.sh

And some lib files are under /lib as the following

/lib/lib1.so    
/lib/lib2.so
/lib/lib3.so

my question I want to create RPM that include my scripts and my lib files !

For example

After I performed (rpm installation) :

rpm -i SOME_RPM.rpm

All scripts will be created under /root/dir directory (include directory creation)

And all my lib files will created under /lib directory

Please advice how to create this RPM hopefully it will be step by step (because I read some documents regarding RPM Build package, and it’s hard to understand them

I have a machine running AIX. I'm looking to install rsync on it. Does rsync support AIX? If so, where might I download it?

In case it matters: I will be using rsync to copy a filesystem from my AIX machine to another UNIX machine, so it needs to be compatible with other versions of rsync.

My Linux machine has the following definition:

• RHEL 5.4
• Kernel release.2.6.18

but I don’t have the g++ command. (I need to write c++ programs under Linux)

For example:

 [root@linux /etc]# g++
 -bash: g++: command not found

I also tried the following:

 yum install gcc
 loaded plugins: security
 Setting up Install Process
 No package g++ available.
 Nothing to do

My question: How do I install/download the g++ command? From where can I get g++?

I have the gcc command but this is only for C programs, not C++.

  [root@linux /]# which gcc
  /usr/bin/gcc 

From man page I see: (I'm not sure if gcc also compiles C++)

  [root@linux /]# man gcc
  GCC(1)                                GNU                               GCC(1)

  NAME
  gcc - GNU project C and C++ compiler

please advice:

I want to install perl module but after make command I get gcc - - command not found? yael

# make

gcc -c   -fno-strict-aliasing -pipe -Wdeclaration-after-statement -I/usr/local/include -    D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -c
/bin/sh: gcc: command not found

# find / -name gcc

 /usr/lib/gcc

 # ls -l /usr/lib/gcc

 total 8
 drwxr-xr-x 3 root root 4096 Jan 27 11:36 i386-redhat-linux

Even when /tmp has no file called something, searching for it with find will return 0:

  $ find /tmp -name something 
  $ echo $?
  0

How can I get a non-zero exit status when find does not find anything?

I connect USB (hard disk ) to my Linux machine

the USB recognized as /dev/sdb1 ( by fdisk –l)

The hard disk include some data as images , tar files etc……

How to mount the USB? (/dev/sdb1) in order to read the data from the USB?

why the following command " find / -name 'node1' -print0 | xargs -0 rename 's/node1/node_STAR/' " not replace the node1 under /var/tmp directory?

my target is to scan linux sys and rename directories and files

example from my linux machine

pwd
/var/tmp/Change_host_dir
find  /  -name '*node1*'  -print0 | xargs -0
/var/tmp/Change_host_dir/node1
find  /  -name '*node1*'  -print0 | xargs -0 rename 's/node1/node_STAR/'
ls
node1

I need to scan all directories & files ander / directory And to rename the host - "node1" with "node_STAR" in file name or directory name

Can some one have brilliant idea how to do that maybe with find or perl ( in order to insert this to my shell script) Any way it's must be very fast in spite we scananing all Linux directories and files

example on - file

     /var/tmp/node1 will be /var/tmp/node_STAR file

example on - directory

     /etc/my_hosts/node1  will be /etc/my_hosts/node_STAR dir

According to the rsync man page:

-a, --archive This is equivalent to -rlptgoD. It is a quick way of saying you want recursion and want to preserve almost everything (with -H being a notable omission). The only exception to the above equivalence is when --files-from is specified, in which case -r is not implied.

Note that -a does not preserve hardlinks, because finding multiply-linked files is expensive. You must separately specify -H.

It seems that we must use the -H option in order to copy also hard links (really?).

But according to my tests even if I don't use the -H option, rsync copied the hard link successfully from the local directory to another machine. This seems strange to me.

For example

$ ls -ltr
  -rw-r--r-- 1 root root 0 Jan 20 15:06 test.file.hard.link
  -rw-r--r-- 1 root root 0 Jan 20 15:06 test.file

$ rsync -Wav --progress /var/tmp/Backup_test_for_hard_link node1:/var/tmp

In node1 under /var/tmp, I see the hard link files:

-rw-r--r-- 1 root root 0 Jan 20 15:06 test.file.hard.link
-rw-r--r-- 1 root root 0 Jan 20 15:06 test.file

How can this be explained?

3. is it posible to define bond0:0 when I have only one LAN (eth0)
