Storing command output in a variable and using cut/awk

Hi,

My aim is to get the md5 hash of a file and store it in a variable.


var1="md5sum file1"
$var1


The above outputs fine but also contains the filename, so somthing like this 243ASsf25 file1

i just need to get the first part and put it into a variable.


var1="md5sum file1"
$var1 | awk '{print $1}'


This only prints the first part which is what i want but i dont know how to put it into a variable to use later on

mysqli_stmt::bind_result - Binds variables to a prepared statement for result storage

       Object oriented style

SYNOPSIS
bool mysqli_stmt::bind_result (mixed &$var1, [mixed &$...]) DESCRIPTION
Procedural style bool mysqli_stmt_bind_result (mysqli_stmt $stmt, mixed &$var1, [mixed &$...]) Binds columns in the result set to variables. When mysqli_stmt_fetch(3) is called to fetch data, the MySQL client/server protocol places the data for the bound columns into the speci- fied variables $var1, .... Note Note that all columns must be bound after mysqli_stmt_execute(3) and prior to calling mysqli_stmt_fetch(3). Depending on column types bound variables can silently change to the corresponding PHP type. A column can be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect the next time mysqli_stmt_fetch(3) is called. PARAMETERS
o $ stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3). o $var1 - The variable to be bound. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Object oriented style <?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); if (mysqli_connect_errno()) { printf("Connect failed: %s ", mysqli_connect_error()); exit(); } /* prepare statement */ if ($stmt = $mysqli->prepare("SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) { $stmt->execute(); /* bind variables to prepared statement */ $stmt->bind_result($col1, $col2); /* fetch values */ while ($stmt->fetch()) { printf("%s %s ", $col1, $col2); } /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?> Example #2 Procedural style <?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (!$link) { printf("Connect failed: %s ", mysqli_connect_error()); exit(); } /* prepare statement */ if ($stmt = mysqli_prepare($link, "SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) { mysqli_stmt_execute($stmt); /* bind variables to prepared statement */ mysqli_stmt_bind_result($stmt, $col1, $col2); /* fetch values */ while (mysqli_stmt_fetch($stmt)) { printf("%s %s ", $col1, $col2); } /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?> The above examples will output: AFG Afghanistan ALB Albania DZA Algeria ASM American Samoa AND Andorra SEE ALSO
