Variable in bash is not particularly cool until we have a good use of it 😛
> filename="myfile.txt" > touch $filename > ls filename myfile.txt > rm $filename > ls $filename ls: myfile.txt: No such file or directory > files="file1 file2" > touch $files > ls $files file1 file2
In unix, type command tells us whether a keyword is taken by the system or not. It is useful when trying to add a new custom command in the terminal and ensure that our command is not in conflict with system ones.
> type test test is a shell builtin > type cp cp is /bin/cp > type foo -bash: type: foo: not found # This is my custom command > type note note is hashed (/Users/.../bin/note)
