check, that a script is in a folder

2011-01-05 Thread S Mathias 
$ echo ${PWD##*/}
somefolder
$ if ${PWD##*/} -eq asdf  /dev/null; then echo this is the asdf folder; 
else exit 1; fi
bash: notthatfolder: command not found...
this is the asdf folder
$ 


So i just want to check that i'm in an exact folder. e.g.: asdf

What's wrong with my one-liner?

I just want to check, that a script is in a folder, and if it isn't, then it 
exits

Why not simple use:

if [ -e $SCRIPT ]; then
  echo File exists;
else
  echo File does not exist;
fi

Hello,

S Mathias a écrit :

 folder; else exit 1; fi
 bash: notthatfolder: command not found...
 this is the asdf folder
 
 What's wrong with my one-liner?

Two mistakes :
1) if expects a command, not a boolean expression. Use test
expression or [ expression ] to evaluate the expression.
2) -eq is the equal operator for numeric integers, not strings. Use
= for string comparison.

thank you, the:

if ! [ ${PWD##*/} == asdf ]; then echo error: not the asdf dir; exit 1; fi

worked! :)

Note that == is a bashism. = is more portable across other shells
such as dash.
