Question alias with variables
Hi All,

I'm trying to make an alias with a variable inside.

List:
Code:
#########
# files1 #
# files2 #
# files3 #
# wenk1 #
# wenk2 #
# wenk3 #
#########

Code:
 
alias count='while [ 1 ]
do
ls -ltra | grep {print $1} | wc -l
echo =============
sleep 5
done'

#Input:

count files

#Output should be:

Code:
3
=============

#But, it always comes with an error.

Code:
grep: 0652-033 Cannot open -c}.


--Can you help me out?
--Sorry i'm a newbie Smilie

Thanks in advance. Smilie Smilie

This shouldn't work:
Code:
grep {print $1}

Please explain what you're trying to achieve.

Thanks for replying franklin,

I was trying to use the alias like an script.

like when I put:

Code:
count wenk

is displays the count of files:

Code:
3
=============

I also tried to use:

Code:
grep -c {print $1}

And it also doesn't work.

You need to use a function, not an alias:
Code:
count() {
.....
}

Code:
grep {print $1}

You seem to be conflating grep and awk. Like Franklin says: this will never work.
Please explain what you're trying to achieve and what do you mean with a "list" ?
