As you have been shown you can pipe the ls command to another program that further parses the output, in this case awk.
awk can do a lot of things, but even in its simplest form it can be very...

Look into the command touch

if ( ${cnt} -ge "1" ) That reads if cnt is greater or equal to 1 therefore != would have not worked.

if ($cnt >= 1) then
# whatever you want to mail
endif

csh doesn't use if/fi but rather if/endif. Look at posted script and you'll see you have an if/fi.
BTW csh doesn't have the same conditional operators than bash so -ge doesn't work.

Find any difference between both and then match it. e.g. with HOOK by itself in a line we can match the beginning and end of the line. Thus:
grep '^HOOK$' file_name
Once you have down the...

It makes a difference the quotation scheme.
sed "/$npname.*in/d" parts.txt > parts.tmp

What's the trouble?
In its simplest form, create another executable script with three lines of text, where each line is the absolute path to those three scripts.

Assuming data format:


For example purposes coming from datafile to awk and displaying to standard output. Modify to need.

awk '/s/ {
if ( index($2, "GB") ) {
$2 =...

result=$(echo $var1 $var2 | awk '{print $1 - $2}')
$1 inside awk becomes whatever variable you past first, and $2 becomes the second variable and so on.

echo $1 | sed -e "s/^[^=]*=\(.*\)$/\1/"
echo $1 is the argument from the shell piped to sed but it doesn't have any thing to do with \1


What's \1? The first group remembered from the original...
