Or you can simply add -depth to your find command and execute rmdir, ignoring eventual errors (/dev/null).
In addition, some find implementations support the -empty flag.
In addition, some find implementations (like GNU find, for instance) support the -empty option:
Quote:
-empty File is empty and is either a regular file or a directory.
Hi folks,

Sample file:
This is line one,
this is another line,
this is the PRIMARY INDEX line

This is another line
The command should find the line with “PRIMARY INDEX” and remove the last character from the line preceding it (in this case , comma) and remove the first character from the line... (5 Replies)
Hi ,
I am doing some enhancements in an existing shell script. There it used the awk command in a function as below :
float_expr() {
IFS=" " command eval 'awk "
BEGIN {
result = $*
print result
exit(result == 0)
}"'
}
It calls the function float_expr to evaluate two values ,... (1 Reply)
Hi,
I have a file with more than 1000 lines. Most of the lines have 16 characters. I want to find out lines that have less than 14 characters (usually 12 or 13).
wc -l gives me the line count and wc -c gives me the total characters in a file. I could not get the total characters for each line.... (1 Reply)
Hello All,
I got a requirement when I was working with a file. Say the file has unloads of data from a table in the form

I need the character count of the last line of each file in a directory, and not the total.
Now I have been doing this but unfortunately, -exec doesn't support pipes:
find sent/ -type f -exec tail -1|wc -c {} \;
If I try this:
find sent/ -type f -exec tail -1 {} \; | wc -c
It will give... (6 Replies)

sort
SORT(1) User Commands SORT(1)NAME
sort - sort lines of text files
SYNOPSIS
sort [OPTION]... [FILE]...
sort [OPTION]... --files0-from=F
DESCRIPTION
Write sorted concatenation of all FILE(s) to standard output.
Mandatory arguments to long options are mandatory for short options too. Ordering options:
-b, --ignore-leading-blanks
ignore leading blanks
-d, --dictionary-order
consider only blanks and alphanumeric characters
-f, --ignore-case
fold lower case to upper case characters
-g, --general-numeric-sort
compare according to general numerical value
-i, --ignore-nonprinting
consider only printable characters
-M, --month-sort
compare (unknown) < `JAN' < ... < `DEC'
-n, --numeric-sort
compare according to string numerical value
-R, --random-sort
sort by random hash of keys
--random-source=FILE
get random bytes from FILE (default /dev/urandom)
-r, --reverse
reverse the result of comparisons
--sort=WORD
sort according to WORD: general-numeric -g, month -M, numeric -n, random -R, version -V
-V, --version-sort
sort by numeric version
Other options:
--batch-size=NMERGE
merge at most NMERGE inputs at once; for more use temp files
-c, --check, --check=diagnose-first
check for sorted input; do not sort
-C, --check=quiet, --check=silent
like -c, but do not report first bad line
--compress-program=PROG
compress temporaries with PROG; decompress them with PROG -d
--files0-from=F
read input from the files specified by NUL-terminated names in file F; If F is - then read names from standard input
-k, --key=POS1[,POS2]
start a key at POS1 (origin 1), end it at POS2 (default end of line)
-m, --merge
merge already sorted files; do not sort
-o, --output=FILE
write result to FILE instead of standard output
-s, --stable
stabilize sort by disabling last-resort comparison
-S, --buffer-size=SIZE
use SIZE for main memory buffer
-t, --field-separator=SEP
use SEP instead of non-blank to blank transition
-T, --temporary-directory=DIR
use DIR for temporaries, not $TMPDIR or /tmp; multiple options specify multiple directories
-u, --unique
with -c, check for strict ordering; without -c, output only the first of an equal run
-z, --zero-terminated
end lines with 0 byte, not newline
--help display this help and exit
--version
output version information and exit
POS is F[.C][OPTS], where F is the field number and C the character position in the field; both are origin 1. If neither -t nor -b is in
effect, characters in a field are counted from the beginning of the preceding whitespace. OPTS is one or more single-letter ordering
options, which override global ordering options for that key. If no key is given, use the entire line as the key.
SIZE may be followed by the following multiplicative suffixes: % 1% of memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y.
With no FILE, or when FILE is -, read standard input.
*** WARNING *** The locale specified by the environment affects sort order. Set LC_ALL=C to get the traditional sort order that uses
native byte values.
