Do any of the 350,000 files you're moving have names that contain any space, tab, or newline characters?
Hi Don,
I am on Ubuntu Server 12.04 LTS. The files do not contain any special characters except _
Actually the format is something like
<xyz>_n1_n2_n3.pbx
where <xyz> is a prefix containing only alphabets [a-z A-Z]
n1 is a number less than 10
n2 is a number less than 1000
n3 is a number less than 10000
pbx is the extension

Safer and faster is
Thanks.. Although I did not get an error for too many files with for I in *, find seems faster and as you mentioned safer if the number of files increase.
Hi,
I want to write a script that deletes all folders and keep the last 10 recent folders.
I know the following:
ls -ltr will sort the folders from old to recent.
ls -ltr | awk '{print $9}' will list the folder names (with a blank line at the beginning)

Hi, all:
I've got two folders, say, "folder1" and "folder2".
Under each, there are thousands of files.
It's quite obvious that there are some files missing in each. I just would like to find them. I believe this can be done by "diff" command.
However, if I change the above question a... (1 Reply)

I met a problem on HPUX with 64G RAM and 20 CPU.
There are 5 million files with file name from file0000001.dat to file9999999.dat, in the same directory, and with some other files with random names.
I was trying to remove all the files from file0000001.dat to file9999999.dat at the same time.... (9 Replies)
I’m new to Linux script and not sure how to filter out bad records from huge flat files (over 1.3GB each). The delimiter is a semi colon “;”

OD(1) FSF OD(1)NAME
od - dump files in octal and other formats
SYNOPSIS
od [OPTION]... [FILE]...
od --traditional [FILE] [[+]OFFSET [[+]LABEL]]
DESCRIPTION
Write an unambiguous representation, octal bytes by default, of FILE to standard output. With more than one FILE argument, concatenate
them in the listed order to form the input. With no FILE, or when FILE is -, read standard input.
All arguments to long options are mandatory for short options.
-A, --address-radix=RADIX
decide how file offsets are printed
-j, --skip-bytes=BYTES
skip BYTES input bytes first
-N, --read-bytes=BYTES
limit dump to BYTES input bytes
-s, --strings[=BYTES]
output strings of at least BYTES graphic chars
-t, --format=TYPE
select output format or formats
-v, --output-duplicates
do not use * to mark line suppression
-w, --width[=BYTES]
output BYTES bytes per output line
--traditional
accept arguments in traditional form
--help display this help and exit
--version
output version information and exit
Traditional format specifications may be intermixed; they accumulate:
-a same as -t a, select named characters
-b same as -t oC, select octal bytes
-c same as -t c, select ASCII characters or backslash escapes
-d same as -t u2, select unsigned decimal shorts
-f same as -t fF, select floats
-h same as -t x2, select hexadecimal shorts
-i same as -t d2, select decimal shorts
-l same as -t d4, select decimal longs
-o same as -t o2, select octal shorts
-x same as -t x2, select hexadecimal shorts
For older syntax (second call format), OFFSET means -j OFFSET. LABEL is the pseudo-address at first byte printed, incremented when dump is
progressing. For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal, suffixes may be . for octal and b for multiply by 512.
TYPE is made up of one or more of these specifications:
a named character
c ASCII character or backslash escape
d[SIZE]
signed decimal, SIZE bytes per integer
f[SIZE]
floating point, SIZE bytes per integer
o[SIZE]
octal, SIZE bytes per integer
u[SIZE]
unsigned decimal, SIZE bytes per integer
x[SIZE]
hexadecimal, SIZE bytes per integer
SIZE is a number. For TYPE in doux, SIZE may also be C for sizeof(char), S for sizeof(short), I for sizeof(int) or L for sizeof(long). If
TYPE is f, SIZE may also be F for sizeof(float), D for sizeof(double) or L for sizeof(long double).
RADIX is d for decimal, o for octal, x for hexadecimal or n for none. BYTES is hexadecimal with 0x or 0X prefix, it is multiplied by 512
with b suffix, by 1024 with k and by 1048576 with m. Adding a z suffix to any type adds a display of printable characters to the end of
each line of output. --string without a number implies 3. --width without a number implies 32. By default, od uses -A o -t d2 -w 16.
