adding contents of a variable to a command

gammarays · #1 (**permalink**) 02-07-2005

hi all,

i'm new to shell scripting, so i'm not sure how to work this. Is it possible to read in the contents of a variable and add it to a command? for example:

------------------------
#!/bin/sh

set example = -dfr

rm ${example}
------------------------
when i run the script, i want it to do a rm -dfr. Right now, it doesn't seem to work, and i'm not sure what i'm doing wrong

Use the syntax:
example="-dfr"

No spaces around the equal sign.
