Re: c shell question

#searches for line containing string "Author" (from file ./tcase/$1/$1.v where $1 is
# first argument passes to this script) on this line the 2nd, 3rd, 4th and 5th
# words get assigned to $ow

set ow = `awk '/Author/ {print $2,$3,$4,$5}' ./tcase/$1/$1.v`
# this will search for "test_case" in transport_tb.v file and replce it with $1 the result will
# be stored in $1_tb.v file
sed s/test_case/$1/g < transport_tb.v > $1\_tb.v

# store current date and time in temp1 file
date >! temp1

# this will set $tm to 16:42:33(Aug/25)
set tm = `awk '{print $4"("$2"/"$3")"}' temp1`

I will advice you to run commands one by one and see yourself whats happening.
you can get help by using man for awk and ed

Hope this helps
