[gentoo-user] Bash script inquiry

[Richard Marza]

I'm trying to run a command in a loop. I have a counter device set...the 
number that the counter generates is supposed to go inside the command in 
the loop after every successive iteration of the loop. This is all really to 
get a general idea I've attached a snippet below.

FILE=`cat filename.txt`
TICK=`cat filename.txt | wc -l'
TOCK="0"

while [ $TICK != $TOCK ] ; do
            let $TOCK=$TOCK+1
            Var1= `cat FirstWordOfFirstColumnOfFirstLine` (This I actually 
achieved with sed and awk)
            Var2=`cat FirstFloatOfFirstLine`   (The problem lies here; it's 
my inability to come up with a way of implementing a variable that changes 
along with the counter.  so that the second time this is run it doesn't do 
the first line but moved to the second line and the third line and so on...)

done

exit 0



My file is like so:


Variable        Sys1    Sys2            Sys3            Sys4      Sys5


Dbase1          5.0       4.6              5.6              6. 6       .004
