nested 'if' statement
Once more a very beginners question: what is wrong in my second 'if' statement?
PHP Code:
# my shell arguments
NB_ARGS=$#
ARGS=$@
echo arguments\: $ARGS; echo

# inspect arguments
if [[ $# -lt 3 && $# -ge 1 ]]; then
  echo now_in_first_if               # here's line 23
  if [[ "$1" -eq "deploy" ]]; then  # this gives the error
    echo blaaaaaaaat
  fi
fi 
When I launch the script:
PHP Code:
st25219@mx73:ian$ deliver.ksh deploy 
it gives an error message:
PHP Code:
arguments: deploy

now_in_first_if
deliver.ksh[23]: deploy: bad number 
If I change the 'if' statement in a simple
PHP Code:
if [ -z "$1" ] 
then things work fine.

I do compare the string "deploy" in a correct way, don't I?


ps: When I use single square brackets '[ ]' instead of double square brackets '', it still raises the error, but now it continues the rest of the script (some simple 'echo's, which I haven't shown here).

-ep is used to compare the numeric values ... To compare the string use this

Code:
if [ "$1" == "deploy" ]; then 
      echo "match"
fi

Since you are using ksh, it is also legal to leave out the double quotes i.e.
Code:
if [[ $1 == deploy ]]; then
   echo blaaaaaaaat
fi
