Concat strings without spaces...
Hello,

I have a very travial question....when i run the below script...how can i change my script that will give me an output pf "this is log_vp1" ....i dont want any spaces between log_vp and 1 or any other character...i know i can set a variable for 1(lets say num is the var) and then do $lv$num but i cant do that...this need to be hardcoded...

Code:
# cat test.sh
lv=log_vp

echo "this is $lv+1"
#
# ./test.sh
this is log_vp+1
#

Code tags for code please, [code]stuff[/code]

What you describe is exactly what hardcoded is... I think you mean dynamic, as in, the name needs to change next time the program runs? What determines how the name changes?

Code:
$ lv=log_vp
$ lv+=1
$ echo $lv
$ log_vp1

Code:
$ lv=log_vp
$ echo ${lv}1
$ log_vp1
