As a part of this script, I need to be able to check if the first argument given matches the first word of file. If it does, exit with an error message; if it doesn't, append the arguments to the file. I understand how to write the
if statement, but not how to use
grep within a script. I understand that
grep will look something like this
grep ^$1 schemas.txt
I feel like this should be much easier than I am making it.
I'm getting an error "too many arguments" on the
if statement. I got rid of the space between
grep -q and then got an error binary operator expected.
if [ grep -q ^$1 schemas.txt ]
echo "Schema already exists. Please try again"
echo "$@" >> schemas.txt
