Hi. I have a script which is deleting files with a particular extension and older than 45 days.The code is:
find <path> -name "<filename_pattern>" -mtime +45 -exec rm {} \;
But the problem is that some important files are also getting deleted.To prevent this I have decide to make a dummy... (4 Replies)
I'm writing a c program to list the files in a given directory but I also want to display the hidden files. I can't figure this out in c. Does anyone know how to do this? Here's the code I have so far:
#include <unistd.h>
#include <stdio.h>
#include <dirent.h>

I have a bunch of hidden files in a directory in AIX. I would like to move these hidden files as regular files to another directory.
Say i have the following files in directory /x
.test~1234~567
.report~5678~123
.find~9876~576
i would like to move them to directory /y as
test~1234~567... (10 Replies)
Find all files in the current directory only excluding hidden directories and files.
For the below command, though it's not deleting hidden files.. it is traversing through the hidden directories and listing normal which should be avoided.
`find . \( ! -name ".*" -prune \) -mtime +${n_days}... (7 Replies)
I wanted to grep some text Recursively, without going through hidden files(.files/.folders)
In my Repo there are lot of .svn folders/subfolders etc.
I dont want to grep in that folders.
Hidden folders can be .svn or .<anyotherfoldername>
Can you give teh command whcih does it "Recursively" (5 Replies)
Hello.
I use this command :
rsync -av --include=".*" --dry-run "$A_FULL_PATH_S" "$A_FULL_PATH_D"The data comes from the output of a find command.
And no full source directories are in use, only some files.
Source example... (2 Replies)

sum
sum(3tcl) Cyclic Redundancy Checks sum(3tcl)__________________________________________________________________________________________________________________________________________________NAME
sum - Calculate a sum(1) compatible checksum
SYNOPSIS
package require Tcl 8.2
package require sum ?1.1.0?
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ]
_________________________________________________________________DESCRIPTION
This package provides a Tcl-only implementation of the sum(1) command which calculates a 16 bit checksum value from the input data. The
BSD sum algorithm is used by default but the SysV algorithm is also available.
COMMANDS
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ]
The command takes string data or a file name or a channel and returns a checksum value calculated using the sum(1) algorithm. The
result is formatted using the format(3tcl) specifier provided or as an unsigned integer (%u) by default.
OPTIONS -sysv The SysV algorithm is fairly naive. The byte values are summed and any overflow is discarded. The lowest 16 bits are returned as the
checksum. Input with the same content but different ordering will give the same result.
-bsd This algorithm is similar to the SysV version but includes a bit rotation step which provides a dependency on the order of the data
values.
-filename name
Return a checksum for the file contents instead of for parameter data.
-channel chan
Return a checksum for the contents of the specified channel. The channel must be open for reading and should be configured for
binary translation. The channel will no be closed on completion.
-chunksize size
Set the block size used when reading data from either files or channels. This value defaults to 4096.
-format string
Return the checksum using an alternative format template.
EXAMPLES
% crc::sum "Hello, World!"
37287
% crc::sum -format 0x%X "Hello, World!"
0x91A7
% crc::sum -file sum.tcl
