Top Forums Shell Programming and Scripting How to extract timestamp from the filename? Post 302425888 by av_vinay on Monday 31st of May 2010 03:34:23 AM

I tried with the cut option, with which I am able to extract first date field, but it is not extracting time string as in :


Code:
dateStr=$(echo name_abc_20100531_142528.txt | cut -d_ -f3)

timeStr=$(echo name_abc_20100531_142528.txt | cut -d_ -f4)

echo $dateStr "   " $timeStr

Its printing:

20100531 142528.txt


But my desired o/p should be:

20100531 142528

Help me out to extract the field without the file extension.


Thanks.,

mb_strcut - Get part of string

SYNOPSIS
string mb_strcut (string $str, int $start, [int $length = NULL], [string $encoding = mb_internal_encoding()]) DESCRIPTION
mb_strcut(3) extracts a substring from a string similarly to mb_substr(3), but operates on bytes instead of characters. If the cut position happens to be between two bytes of a multi-byte character, the cut is performed starting from the first byte of that character. This is also the difference to the substr(3) function, which would simply cut the string between the bytes and thus result in a malformed byte sequence. PARAMETERS
o $str - The string being cut. o $start - Starting position in bytes. o $length - Length in bytes. If omitted or NULL is passed, extract all bytes to the end of the string. o $encoding -The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used. RETURN VALUES
mb_strcut(3) returns the portion of $str specified by the $start and $length parameters. SEE ALSO
mb_substr(3), mb_internal_encoding(3). PHP Documentation Group MB_STRCUT(3)
