Halo,
2009/12/1 Hari Hendaryanto <har...@csmcom.com>:
#!/bin/bash
if [ -z "`echo $1 | awk '/^[[:space:]]+/{print}'`" ]; then
tambahkan kutip di antara $1, jadi
if [ -z "`echo "$1" | awk '/^[[:space:]]+/{print}'`" ]; then
it work!!! :) thanks
lalu saya install gawk dan jadi jalan. Mungkin pakai egrep (pake "e"
bukan grep biasa, atau pake grep -E) lebih portabel:
#!/bin/sh
echo "$1" | egrep -q ^[[:space:]]
if [ $? == 0 ]; then
echo "NOT OK";
else
echo "OK";
fi
it work juga :)
kesimpulan cuma kekurangan doublequote aja di parameter $1
thanks
