问题 I am trying to run a shell script from python by exporting the python variable to the shell script instead of directly reading them from the user.

问题 I've written a program to assemble .dot files, and want to use Clojure's sh to give a compile command. Specifically, I use the following function to do it: (defn compile-graphviz "Dumps graphviz-string to a file, then compiles it using dot." [graphviz-string] (do (spit "./tree.dot" graphviz-string) (sh "dot -Tpng \"/.tree.dot\" -o\"/.tree.png\""))) However, when I run this, the second part fails, giving the following error message at the REPL: IOException error=2, No such file or directory

I have a variable which has rows (new lines) and columns (tab separated). What I want to do is loop through the rows and get 'Column X' then put that item into a variable so I can do something with that Cell. i.e. echo out for example. There are an unknown number of rows, but known number of columns, so that it is possible to always get
