convert a list from one row to many rows

[alhassani54]

The script below will take the value from tarsds and write it to a file by converting the list from one row list contains many cloumns to many rows contain one column.

'tarsds' could be = null, could be = one value or could be = more than one value.
Is there a way to simplify the script?

Thank you

tarsds="tarsds200.Z"
cnt=1
otarsds=""
while [[ $cnt != 0 ]]
do
ntarsds=`echo $tarsds | cut -d" " -f$cnt-$cnt`
if [[ $ntarsds = $otarsds ]]; then ntarsds=""; fi
if [[ $ntarsds != "" ]]; then
((cnt=cnt+1))
nntarsds=`echo $ntarsds | cut -d"." -f1-1 >>ntarsds1`
otarsds=$ntarsds
else
cnt=0
fi
done
# cat ntarsds1
Tarsds200

or

tarsds="tarsds200.Z tarsds100.Z tarsds400.Z"
cnt=1
otarsds=""
while [[ $cnt != 0 ]]
do
ntarsds=`echo $tarsds | cut -d" " -f$cnt-$cnt`
if [[ $ntarsds = $otarsds ]]; then ntarsds=""; fi
if [[ $ntarsds != "" ]]; then
((cnt=cnt+1))
nntarsds=`echo $ntarsds | cut -d"." -f1-1 >>ntarsds1`
otarsds=$ntarsds
else
cnt=0
fi
done
# cat ntarsds1
tarsds200
tarsds100
tarsds400

Hi,
Try this

LIST=$(cat tards)
for FILE in $LIST
do
    echo $(basename $FILE .Z) >> ntarsds1
done

If you are using a ksh or bash type shell, this function can be used instead of the external basename command:

# Using ksh pattern-matching operators, this function
# replaces the unix basename command.  If a 2nd argument
# exists, strip off the extension.
function basename {
   typeset v x

   v=${1##*/}
   x=${2#.} # get rid of the '.'
   v=${v%.$x}
   echo $v
}
 
bn=$(basename $var)
echo $bn # displays: ttest.c

bn=$(basename $var .c)
echo $bn # displays: ttest
