Bourne shell help in displaying output

[sajithndka]

Hai,

I want to display the process id of a daemon along with its name
eg: pidof java and the output of my script to be

tomcat (pid 123423) is running ...
but if i do like
echo -n "tomcat ("
pidof java
echo -n ) is running

the output is not obtaining in a single line a newline character is inserted after the command "pidof" . if there is any method to remove the newline after the command "pidof" please help

Try this:

#!/bin/bash

echo $(echo -n "tomcat ("
/pidof java
echo -ne "\b) is running" )

Hope this helps.

Thank you for your reply
Unfortunately it is not working saying that

: command not found
test: line 6 /pidof: No such file or directory
) is running

Note: i named the file test

My mistake. Sorry. Sloppy copying and pasting.

Remove the slash from just before the pidof. That leaves this:

#!/bin/bash

echo $(echo -n "tomcat ("
pidof java
echo -ne "\b) is running" )

use printf

use printf

Not sure how printf can be used to remove a newline, care to enlighten us?
As Bill has said, echo is the tool of choice for converting multi-line output to a single line (and losing excessive whitespace).

This will work:

#!/bin/bash

printf "tomcat %s is running" $(pidof java)

some variants of Unix support -n and -e which are not standard due to incompatibilities between BSD and System -V. Using printf will make it kinda "portable" too.
