Splitting a variable at a specific characher
Hey, I'm somewhat new to writing scripts and I keep coming across a problem when I try to split a filename that contains a dash '-'.
For example:
SomeFoo - FooBar.foo
I want to split to SomeFoo and FooBar.foo
I tried using basename and cut but didn't have any luck.
Any suggestions/help?

Hi Everyone,
Is there a way I can print specific lines using sed -n '3,3p' file.dat or awk 'FNR==3' file.dat when using variable?
For example, I have this script (get_line.ksh) that accepts line parameter that a user wanted to print in the file.dat.

krb5_acl_match_string
KRB5_ACL_MATCH_FILE(3) BSD Library Functions Manual KRB5_ACL_MATCH_FILE(3)
NAME
krb5_acl_match_file, krb5_acl_match_string -- ACL matching functions
LIBRARY
Kerberos 5 Library (libkrb5, -lkrb5)
SYNOPSIS
krb5_error_code
krb5_acl_match_file(krb5_context context, const char *file, const char *format, ...);
krb5_error_code
krb5_acl_match_string(krb5_context context, const char *string, const char *format, ...);
DESCRIPTION
krb5_acl_match_file matches ACL format against each line in a file. Lines starting with # are treated like comments and ignored.
krb5_acl_match_string matches ACL format against a string.
The ACL format has three format specifiers: s, f, and r. Each specifier will retrieve one argument from the variable arguments for either
matching or storing data. The input string is split up using " " and " " as a delimiter; multiple " " and " " in a row are considered to
be the same.
s Matches a string using strcmp(3) (case sensitive).
f Matches the string with fnmatch(3). The flags argument (the last argument) passed to the fnmatch function is 0.
r Returns a copy of the string in the char ** passed in; the copy must be freed with free(3). There is no need to free(3) the
string on error: the function will clean up and set the pointer to NULL.
All unknown format specifiers cause an error.
EXAMPLES
char *s;
ret = krb5_acl_match_string(context, "foo", "s", "foo");
if (ret)
krb5_errx(context, 1, "acl didn't match");
ret = krb5_acl_match_string(context, "foo foo baz/kaka",
"ss", "foo", &s, "foo/*");
if (ret) {
/* no need to free(s) on error */
assert(s == NULL);
krb5_errx(context, 1, "acl didn't match");
}
free(s);
