FIELDNUM()¶
Synopsis¶
Return the 1-based offset of a field in a list
Description¶
Search the variable named varname for the string value delimited by delim and return a 1-based offset as to its location. If not found or an error occured, return '0'.
The delimiter may be specified as a special or extended ASCII character, by encoding it. The characters '\n', '\r', and '\t' are all recognized as the newline, carriage return, and tab characters, respectively. Also, octal and hexadecimal specifications are recognized by the patterns '\0nnn' and '\xHH', respectively. For example, if you wanted to encode a comma as the delimiter, you could use either '\054' or '\x2C'.
Example: If ${example} contains 'ex-amp-le', then ${FIELDNUM(example,-,amp)} returns 2.
