Converting bash script to csh
Hi,
I'm a beginner in scripting and I recently wrote a bash script that would've worked fine until I realized it needed to be written in csh. Could someone please show me how to correctly change the syntax from bash to csh in this script? Any help will be greatly appreciated. I can provide more details on the nature of the script if need be.
#!/bin/bash
print "Separating crashlist for today's date? (y/n)"
read choice
case $choice in
y)
crashlist > separate
;;
n)
echo "Please enter date (yyyymmdd)"
read date
crashlist -d $date > separate
;;
esac
whale ()
{
for host in "whale-1" "whale-2" "whale-3" "whale-4"
do
if grep $host separate
then
echo
echo
echo "Jobs above were lost on $host" ; echo ; echo "Total hours lost:"
grep $host separate | awk ' {sum += $11 }; END { print sum } '
echo
echo "Number of jobs lost:"
grep $host separate | awk 'END{print NR}'
echo -n Press Enter to continue ; read
echo
else
echo
echo
echo "No jobs lost on $host." ; echo ; echo -n Press Enter to continue ; read
echo
echo
echo
fi
done
}
dolphin ()
{
for host in "dolphin-1" "dolphin-2" "dolphin-3" "dolphin-4"

if grep $host separate
then

echo
echo "Jobs above were lost on $host" ; echo ; echo "Total hours lost:"

echo
echo "Number of jobs lost:"

ROUND(3) 1 ROUND(3)
round - Rounds a float
SYNOPSIS
float round (float $val, [int $precision], [int $mode = PHP_ROUND_HALF_UP])
DESCRIPTION
Returns the rounded value of $val to specified $precision (number of digits after the decimal point). $precision can also be negative or
zero (default).
Note
PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings.
PARAMETERS
o $val
- The value to round
o $precision
- The optional number of decimal digits to round to.
o $mode
- Use one of the following constants to specify the mode in which rounding occurs.
+--------------------+---------------------------------------------------+
| Constant | |
| | |
| | Description |
| | |
+--------------------+---------------------------------------------------+
| | |
| PHP_ROUND_HALF_UP | |
| | |
| | Round $val up to $precision decimal places away |
| | from zero, when it is half way there. Making 1.5 |
| | into 2 and -1.5 into -2. |
| | |
| | |
|PHP_ROUND_HALF_DOWN | |
| | |
| | Round $val down to $precision decimal places |
| | towards zero, when it is half way there. Making |
| | 1.5 into 1 and -1.5 into -1. |
| | |
| | |
|PHP_ROUND_HALF_EVEN | |
| | |
| | Round $val to $precision decimal places towards |
| | the next even value. |
| | |
| | |
|PHP_ROUND_HALF_ODD | |
| | |
| | Round $val to $precision decimal places towards |
| | the next odd value. |
| | |
