Homework and Emergencies Homework & Coursework Questions Values rotation in array with bash Post 303035322 by RudiC on Tuesday 21st of May 2019 06:39:40 AM

You seem to have some logical errors in your script:
- mixing up array indices with array values (tmp being assigned a value but then used for an index).

- using a constant (2) when the shift span (n) is given.
- outputting the modified array twice instead of comparing the two before and after


How about
Code:
$ array=( $(seq 1 "$box"))
$ echo " Original array : " ${array[*]}
 Original array :  1 2 3 4 5 6 7 8 9 10
$ echo " shift:" $n
 shift: 4
$ array=( $(for ((i=n; i; i--)); do echo -n  ${array[-i]}" "; unset array[-i];  done; echo ${array[@]}) )
$ echo " array shifted : " ${array[*]}
 array shifted :  7 8 9 10 1 2 3 4 5 6

FBSQL_FETCH_ARRAY(3)							 1						      FBSQL_FETCH_ARRAY(3)

fbsql_fetch_array - Fetch a result row as an associative array, a numeric array, or both

SYNOPSIS
array fbsql_fetch_array (resource $result, [int $result_type]) DESCRIPTION
fbsql_fetch_array(3) is a combination of fbsql_fetch_row(3) and fbsql_fetch_assoc(3). An important thing to note is that using fbsql_fetch_array(3) is NOT significantly slower than using fbsql_fetch_row(3), while it provides a significant added value. PARAMETERS
o $ result -A result identifier returned by fbsql_query(3) or fbsql_db_query(3). o $result_type - A constant and can take the following values: FBSQL_ASSOC, FBSQL_NUM, or FBSQL_BOTH. When using FBSQL_BOTH, in addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys. RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows. If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you must the numeric index of the column or make an alias for the column. select t1.f1 as foo t2.f1 as bar from t1, t2 EXAMPLES
Example #1 fbsql_fetch_array(3) example <?php fbsql_connect($host, $user, $password); $result = fbsql_db_query("database", "select user_id, fullname from table"); while ($row = fbsql_fetch_array($result)) { echo "user_id: " . $row["user_id"] . "<br /> "; echo "user_id: " . $row[0] . "<br /> "; echo "fullname: " . $row["fullname"] . "<br /> "; echo "fullname: " . $row[1] . "<br /> "; } fbsql_free_result($result); ?> SEE ALSO
