Such badness can be done.

Use -z for that. -z tests if a string is blank.

if [ ! -z "$2" ]
then
echo "value $2"
else
echo "2 is blank"
fi

And don't leave out the quotes. [ ! -z ] is a syntax...

Actually, this already accounts for it. See the shift statements. They remove the first argument and move everything down. That's why I can just check $1 every loop.

i.e. if $1=a, $2=b, $3=c,...

I haven't seen that getopt actually makes shell code any simpler...

while [ "$#" -gt 0 ]

case "$1" in

It takes advantage of the greedy matching characteristic of sed, which means that it will try to find the longest match possible.. So in this case the longest match to .*/ is /home/guru/temp/, so it...

Try this:

awk -F'"' '{gsub("[:/]","",$2); print $0; }' myFile

nawk -f glev.awk qq='"' myFile
glev.awk:

No, it expand before the file is removed
rm abc ab*expand to
rm abc abc abd abe abf abg abhso the abc file appears twice
when trying to remove the second one, the file is not found because it...

The _ is an array name. You can change it to whatever valid identifier name you like - !my_awk_array[$0]++ would be the same.

! is a logical negation: NOT my_awk_array[$1]++

The expression...

Or using find properly: The "!" means "not".

# Just the names
find . -type f ! -name '*.jar' -print
# With directory listing
find . -type f ! -name '*.jar' -exec ls -lad {} \;

try:
find ./ -exec ls {} \; |grep -v .jpg

This is the one of the most frequently asked questions :)
