What does the editor have to do with it? You can write a script in any editor, or even directly on the command line.

I AHVE TRIED THIS

for i in 1 2 3 4
do
for j in $i
do
echo "*"
done
done

Why do you expect $i to be interpreted as more than one argument in the inner loop, but not in the outer one?

You can use two loops if you want:

Code:
for i in 1 2 3 4
do
           j=0
           while [ $j -lt $i ]
           do
                      printf "%s" "*"
                      j=$(( $j + 1 ))
          done
          echo
done

But you only need one loop:

Code:
star=*
for i in 1 2 3 4
do
  printf "%s\n" "$star"
  star=$star*
done

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
