While loop with Multiple variables
Hi ,
I am trying to write a script in kshell with while loop ,its like
count=1
count_cmp=1

while [ ${count} -le ${file_length} && ${count_cmp} -le ${count} ]; do

tail -$count tempfile | head -1 > tempstring
.......
done
However i get CIF.sh: line 33: [: missing `]'
I have checked thetrailing spaces , not sure what is wrong here

Hi Amit,

Before answering your question, I have a suggestion for you. If you post the scripts please use the code tags available.

Try this,

Code:
while [ ${count} -le ${file_length} ] && [ ${count_cmp} -le ${count} ];

Each condition in the while loop or if loop should be marked with [ ].


Regards,
Chella

Another way :
Code:
while [ ${count} -le ${file_length} -a ${count_cmp} -le ${count} ]
