How to run multiple piped commands in a find -exec statement?
I can't get this to work. Running a single command works fine:
gives me the file name and number of lines in each .dat file in the directory.
But what if I want to pipe commands, e.g. to grep something and get the number of lines with that pattern in each file?
These both give me syntax errors:
I tried quoting the whole piped expression both ways as well:
These both run without errors but neither produces any output (and there are XXX patterns in the files).
How do I write this command?
Thanks.

I need a command, which could run mutliple commands from a file.
Let's say, I have
mv fileA1 fileB1
mv fileA2 fileB2

Hi Gurues,
I need to modify an existing script that uses find to search a folder, and then move its contents to a folder. What I need to do is run gzip on each file after it's moved.
So, I ran this little test:
Put a ls.tar file on my $HOME, mkdir tmp, and then:

LEARN ABOUT PHP
pdo.exec
PDO.EXEC(3) 1 PDO.EXEC(3)PDO ::exec - Execute an SQL statement and return the number of affected rows
SYNOPSIS
public int PDO::exec (string $statement)
DESCRIPTION PDO.exec(3) executes an SQL statement in a single function call, returning the number of rows affected by the statement.
PDO.exec(3) does not return results from a SELECT statement. For a SELECT statement that you only need to issue once during your program,
consider issuing PDO.query(3). For a statement that you need to issue multiple times, prepare a PDOStatement object with PDO.prepare(3) and
issue the statement with PDOStatement.execute(3).
PARAMETERS
o $statement
- The SQL statement to prepare and execute. Data inside the query should be properly escaped.
RETURN VALUES PDO.exec(3) returns the number of rows that were modified or deleted by the SQL statement you issued. If no rows were affected, PDO.exec(3)
returns 0.
Warning
This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on
Booleans for more information. Use the === operator for testing the return value of this function.
The following example incorrectly relies on the return value of PDO.exec(3), wherein a statement that affected 0 rows results in a call to
die(3):
<?php
$db->exec() or die(print_r($db->errorInfo(), true));
?>
EXAMPLES
Example #1
Issuing a DELETE statement
Count the number of rows deleted by a DELETE statement with no WHERE clause.
<?php
$dbh = new PDO('odbc:sample', 'db2inst1', 'ibmdb2');
/* Delete all rows from the FRUIT table */
$count = $dbh->exec("DELETE FROM fruit WHERE colour = 'red'");
/* Return number of rows that were deleted */
print("Deleted $count rows.
");
?>
The above example will output:
Deleted 1 rows.
