As the title says, I am trying to determine if my bash script receives a full path or a relative file to a directory as a parameter.
For some reasons the following doesn't seem to work for me:
#!/bin/bash
DIR=$1
if [ "$DIR" = /* ]
then
echo "absolute"
else
echo "relative"
fi
./script.sh: line 5: [: too many arguments
relative
[ ... ]
doesn't do pattern matching. /*
is being expanded to the contents of /
, so effectively you have
if [ "$DIR" = /bin /boot /dev /etc /home /lib /media ... /usr /var ]
or something similar. Use [[ ... ]]
instead.
if [[ "$DIR" = /* ]]; then
