Remove extra character

Hi

I am using cat <filename> command in one of my datastage job(Command Activity). It is giving actual value but giving extra line.


Eg: Displayed Output: 1 and showing extraline(Eg: 1
) I had checked even wc -c it is giving one character extra.

If the file contains 11. wc -c says 3.

This input file is being created by echo <Parameter> > Filename. in one of my datastge job.

Can anybody advise how to read exact value.
Input file may vary in length depends on the parameter value.

Code:
~/tmp$ echo 1 > file
~/tmp$ cat file
1
~/tmp$ value=$(cat file);printf "$value"
1~/tmp$

# 3

By your second example

and the fact that you are testing with wc -c, I think that you mean characters and not lines. If that is so, then it is depends on the value of

<Parameter>

i had passed 1 as parameter value.

If you can see in the first example there is space in the second line after 11.

How can we skip the extra line or character?
