If else condition
Hi,

I am writing a script and using if condition as per below example.
Code:
echo $abspath
echo if [[ -f "$abspath" ]] 
then 
echo "file exist" 
fi

but this never satisfy the condition even if i am giving correct path to it. and this works on command prompt correctly.

Please help me out in finding the root cause of it.

Thanks,
Vipin Kumar Rai

You seem to have found the error in your first script - does the problem persist or is it solved? Please provide an indication of the status of the thread.

Too bad! Please describe your problem in detail. On two installations (linux & FreeBSD) your script yields
Code:
abspath=/mnt/9/playground/leapfunction 
if [[ -f "$abspath" ]] 
then 
echo "file exist" 
fi
file exist

seems to work flawlessly.

You could give us the error message you are getting...
I suspect you are using a true sh shell that doesnt recognise [[ syntax ...
Try
Code:
echo $abspath
if [ -f "$abspath" ] 
then 
   echo "file exist" 
fi

If this works, I hope you see why we insist on knowing the shell you are using and your OS...

Demonstration:
Code:
onas:/home/vbe $ cat test002
abspath=./test003 
if [ -f "$abspath" ]
then 
   echo "$abspath file exist " 
fi
onas:/home/vbe $ sh test002
./test003 file exist 
onas:/home/vbe $ ksh test002
./test003 file exist 
onas:/home/vbe $ cat test003
abspath=./test003 
if [[ -f "$abspath" ]]
then 
   echo "$abspath file exist " 
fi
onas:/home/vbe $ ksh test003
./test003 file exist 
onas:/home/vbe $ sh test003
test003: 5: [[: not found
onas:/home/vbe $

HI,

Thanks for you suggestion.
The problem was "^M" getting appended in the variable.
can you please let me know if i want to check the value if it has ^M, how to display then.

Thanks,
Vipin Kumar Rai

---------- Post updated at 08:30 AM ---------- Previous update was at 08:28 AM ----------

for eg.
Code:
abc="i am vipin^M"
cat $abc

it is not showing "^M" character but i want to show it.
what is the way?
