not when $NF is 0

Hi rprpr,

unix.com is not a place where the members do your work for you, regardless of if it is homework, personal or professional work.

We are here to help you do your work, not do your work...

Another important information is how the scripts are started.
Would it be possible to have a wrapper script to start those 3 scripts in background and use the wait command to wait for all of them to...

Wouldn't it be nice to tell people the sort criteria?

How about
paste -s -d" \n" file | tr -s ' ' ' '
array([ 0.03015278, 0.02738889, 0.0125 , 0.00875 , 0.00736806, 0.00672917, 0.00763889, 0.01044444, 0.01178472, 0.01470139, 0.02020833,...

If you know the first and last ID, why not generate the sequence yourself:
[user@host ~]$ seq -f "RETT-%.0f" 1 5
RETT-1
RETT-2
RETT-3
RETT-4
RETT-5

Hello Shamrock,

Thank you for nice code, would like to add here IMHO. Above code gives extra string at last from ActiveTechorActiveClerk, so to remove them too just a little modification of you...

Hi.

Also a script with a utility written in perl:
#!/usr/bin/env bash

# @(#) s1 Demonstrate combinations of 2 from list of strings in file.

# Utility functions: print-as-echo,...

Another way to count the number of (non-hidden) entries in a directory in pure shell, which is also more accurate (it will count filenames that contain newlines correctly):
set -- *; echo $#

or...

Small simplification of shamrock's well working proposal:
awk 'BEGIN{while(getline < "f1" > 0) x[$2]=$0} $2 in x && $3>40 && $4>49 {print x[$2]}' f2
1 100 A C
1 1000 - G

Orawk '{$2+=0}1' CONVFMT="%.2f" file

Probably due to EAGL€'s insistence on posting extremely long one-liners, you missed that there is also a trailer line being printed. To take care of that you need to add an END clause...
END{printf...

Try:
awk '!H[$2]++' infile

Or using sort you could sort on 2nd field and print 1st of an equal run, then re-sort back into numeric order on field 1:

sort -u -k 2,2 infile | sort -n

Hi yifangt,
You are aware that you can access shell scripts from C code using the system() function, aren't you?

Although it is not a well known fact, all awk releases are able to retrieve the current epoch time by standard :
$ awk 'BEGIN {srand();time=srand();print time}'
1416532245

This is implementation dependent.

$ strace ed file.txt 2>trace
q
$ grep "/tmp/" strace
open("/tmp/tmpfpHh7ZE", O_RDWR|O_CREAT|O_EXCL, 0600) = 3
unlink("/tmp/tmpfpHh7ZE") = 0
$
...

Try your code on the following March 30, 2014. There is no February 30th.

RudiC,
When I try:
sed -E 's/(;|.)$/;/' MyFile.csv
it replaces the last character on every line with a semicolon instead of adding a semicolon to the end of lines that don't already have one.
...

Op should be csv, I think

Hi.

Standard HPUX utility csplit is designed for this. For example, assuming a well-formatted file, this script:
#!/usr/bin/env bash

# @(#) s1 Demonstrate context splitting, csplit.
...

What have you tried? You should be able to solve this new problem by modifying either awk suggestion.

Also, pay attention to how a moderator edited your original post. Use code tags for code and...

Understood, however, the only issue I was trying point out was that because of that bit-wise fun, depending on the error code sent back, it *could* come back as 0, despite throwing an error.
(ie if...

Try this ls *.csv | sort -t_ -k3,3n

awk -F'-[0-9].*' '{print $1}'

Putting the quotes at the right places will make it work:cat file | while read l_line; do echo "$(echo "$l_line" | awk -F',' '{OFS = ",";$1=""; print $0}')"; done
,item, 12345678
