Hmmm... Bash doesn't parse whitespace with a read. lev@sys09:~$ read line; echo "$line" test test You can imagine what this does if you're using a shell script to read a list of unknown file names containing unknown spaces. lev@sys09:~$ read word1 word2; echo "$word1,$word2" 123 456...

Preventing an endless loop with recursive grep

When finding a string in files within a directory, one can use this: grep -r "searchstring" dir/subdir/ > listofoccurrences.txt For brevity sake one can enter the intended directory and use this: grep -r "searchstring" . > listofoccurrences.txt which as I found out leads to an endless loop,...

sqlite_escape_string

SQLITE_ESCAPE_STRING(3) 												   SQLITE_ESCAPE_STRING(3)

sqlite_escape_string - Escapes a string for use as a query parameter

SYNOPSIS

       string sqlite_escape_string (string  $item)

DESCRIPTION

       sqlite_escape_string(3)	will  correctly  quote the string specified by $item for use in an SQLite SQL statement. This includes doubling up
       single-quote characters ( ') and checking for binary-unsafe characters in the query string.

	Although the encoding makes it safe to insert the data, it will render simple text comparisons and LIKE clauses in your  queries  unusable
       for  the  columns  that contain the binary data. In practice, this shouldn't be a problem, as your schema should be such that you don't use
       such things on binary columns (in fact, it might be better to store binary data using other means, such as in files).

PARAMETERS

	      o $item
		- The string being quoted.  If the $item contains a NUL character, or if it begins with a character whose ordinal value  is  0x01,
		PHP will apply a binary encoding scheme so that you can safely store and retrieve binary data.

RETURN VALUES

	Returns an escaped string for use in an SQLite SQL statement.

NOTES

       Note

	       Do  not	use  this  function to encode the return values from UDF's created using sqlite_create_function(3) or sqlite_create_aggre-
	      gate(3) - use sqlite_udf_encode_binary(3) instead.

       Warning

	      addslashes(3) should NOT be used to quote your strings for SQLite queries; it will lead to  strange  results  when  retrieving  your
	      data.

SEE ALSO

       sqlite_udf_encode_binary(3).
