check leading and trailing white space from a variable and fail the script
Hi All ,
I was trying this for some time and can one one please help , consider variable called release has some value called 1.0.11 , i want to check that variable if it has any leading or trailing space and in case if it has any space then the script should fail , how can i achieve this ??
I tried the below code but this does not work
release=1.0.11
```if [ release=${release// } ]; then
echo "release version has trailing or leading whitespaces"
exit 1
else
echo "release version value is fine"
fi```
if [[ $release != ${release// } ]]; then
echo "release version has trailing or leading whitespaces"
exit 1
else
echo "release version value is fine"
fi
Thanks guys , i checked the above code but unfortunately i got the wrong result, the release version is a input parameter text box which will be feed manually , their is lot of chances people leave spaces in front or after enter the version but the code is not picking up the space but not sure why and i got the result as
as release version value is fine when actually i gave release= 1.0.100 and release=1.0.100 (here a space after 100 )
But my requirement is not to trim the space , my requirement is to check for leading and trailing white spaces and if any space is found then the script should fail.
