hostname give the output as
server2.mydomain.com

I need to execute 2 commands in the same line

Code:

hostname ; ls -lt /home/zamo|grep -v total |head -1

It gives me an output like this ;

Code:

server2.mydomain.com
drwxrwxr-x   2 zamo zamo       4096 Oct 31 12:40 myscripts

Inorder to bring the output into a single line I modified the command to

Code:

 echo -ne `hostname` \\t ; ls -lt /home/zamo |grep -v total|head -1

Again inorder to cut the server2.mydomain.com to server2

Code:

echo -e `hostname` |awk -F\. '{print $1F}'  ; ls -lt /home/zamo |grep -v total|head -1

the output is

Code:

server2
drwxrwxr-x   2 zamo zamo       4096 Oct 31 12:40 myscripts

To make the output to a single line, i tried with

Code:

echo -e `hostname` |awk -F\. '{print $1F}'  \\t; ls -lt /home/zamo |grep -v total|head -1
echo -e `hostname` |cut -d '.' -f1,1  \\t; ls -lt /home/zamo |grep -v total|head -1

Both failed to get the desired output

I have an issue in using the \\t after awk -F\. '{print $1F}' and |cut -d '.' -f1,1.

Is there any other option to get my output as

Code:

 server2 drwxrwxr-x   2 zamo zamo       4096 Oct 31 12:40 myscripts

Can't you just use variables, e.g.

hostname=`hostname | awk -F '.' '{print $1}'`
ls_output=`ls -lt /home/zamo|grep -v total |head -1`
echo "$hostname $ls_output"

A correct form of your command (using awk) can be

Code:

echo -e `hostname` |awk -F\. '{printf "%s\t",$1}'  \\t; ls -lt /home/zamo |grep -v total|head -1

where you use printf to avoid the newline character resulting from the print statement. Another simple way (similar to the one suggested by Nylex) is

Code:

echo -e "$(hostname -s)" "\t" "$(ls -lt | grep -v total | head -1)"

or eventually

Code:

printf "%s\t%s\n" "$(hostname -s)" "$(ls -lt | grep -v total | head -1)"

the -s option of hostname gives the short name, without the domain.
