Extra Space in output - remove
Hi All

I am trying to perform the below operation -
Code:
count=`cat abc.txt | wc -l`
 
echo$count
 
5
 
Head=Start"$DATE"00000"$count"File
 
echo $HEAD
 
START15020300000 5File

There is a space coming before 5 which is not needed . How to ignore that .

Try declaring the variable count as an integer before assignment:

Code:
 
typeset -i count
count=`cat abc.txt | wc -l`
etc....

Unix wc has leading spaces.
Work-around:
Code:
count=`grep -c '^' abc.txt`

or
Code:
count=`sed -n '$=' abc.txt`

or
Code:
count=`awk 'END {print NR}' abc.txt`

Could also simply substitute:

Code:
....
Head="Start${DATE}00000${count/ /}File"
...
