Get ideas from this example :
echo "abcdefghij;klmnop;qrstuv;wxyz" | tr ';' '\n' | sort | uniq | awk 'length()<8' | tr '\n' ';'

How is it possible to have plenty of files with the same name in one directory?
Do you mean instead «All files ending with "snps.ivg"» or «All "snps.ivg" in all sub-directories»?
Thanks for...

With GNU date, you can do something like this, in sh or bash:
#!/bin/sh

# Past date in seconds since Epoch
past=$(date +%s --date "12/02/2013 11:21")

# Now in seconds since Epoch
now=$(date...

Just to be clear : input_file's 7th column is what you call 'item list', isn't it?
Do you also mean that you might have aa1 as well as foo, bar, and etc entries only for $7? ab2, fool, bars, etcs...

Nothing fancy in the below script, just an all-in-one task:
awk '{$10=$7;$7=$8=$9="na"}
$10~/aa1/{$7="aa1"}
$10~/ab2/{$8="ab2"}
$10~/ac3/{$9="ac3"}
1' input_file > output_file

awk '$0=i+=5" "$0' file(not tested, I'm on my phone)

Try this one instead :
awk -F, '{A[$1 FS $2] = A[$1 FS $2] ? A[$1 FS $2] FS $NF : $N} END {for ( k in A ) print A[k]}' output/* > output-4.csv

Try also this awk code as well :awk 'NR==FNR{A[++i,1]=$1;A[i,2]=$2;A[i,3]=$3;next}
{j=0;while(j++<i)if(($2==A[j,1])&&($3>=A[j,2])&&($3<=A[j,3]))print}
' filterfile datafile

Edit - Nevermind, don't pay attention to this stupid question.


Is it acceptable to use a range file like this?

EDIT : The solution below does not fit the question, sorry about that :X

Is this OK?~/unix.com$ awk 'BEGIN{n=4; for(i=1; i<=n; i++)print i}'

3

~/unix.com$ awk 'BEGIN{n=4;...

Actually, Scrutinizer's reply is way more simple to use :)
if ! $SERVICE status > /dev/null 2>&1uses exit status as well; in this case if $SERVICE status did not (!) exit with status 0; then rest of...

if [ "$SERVICE status" = 'xinetd is stopped' ]
In this case, "$SERVICE status" is equal to "/etc/init.d/xinetd status", not 'xinetd is stopped'

I suggest you to use exit code instead of what is...

Wow! :D It took me some time to figure out what was going on in this tiny script ^^

Thanks Corona688 for your input !
Here is another solution using AWK:
~/unix.com$ awk '{gsub("\r","");print > "file"$NF".txt"}' RAW

I suspect your RAW file to have \r\n at the end of each line (typically all txt files created from MS Windows notepad). You have to remove \r from the original file. Try (not tested)
tr '\r\n' '\n'...

awk '{print > "file"$NF".txt"}' RAW

awk '{print > $3".txt"}' EDIT.txt

awk '{print > $NF".txt"}' RAW

Actual Debian Testing (Jessie) also uses gawk after a "standard system" install.
You still get mawk if you choose to not install the "Standard system" at Tasksel install step.

The external command seq 24 might come in handy.

Any value between 0 and $(date +%s) can be an epoch value

Try this link:
Index of /pub/mozilla.org/firefox/releases/19.0.2 (http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/19.0.2/)

Give this one go, https://www.unix.com/302107299-post2.html
It worked fine with /bin/sh and /bin/bash on Debian Testing

man bash (or any shell that supports getopts) and find the getopts function

You can try using the rsync delete options, but you have to be very careful with these.
--del an alias for --delete-during
--delete delete...

Quite the same solution as Corona688; uses aplay to play wav files:
#!/bin/sh

while read line; do
set -- $line
while [ "$1" ]; do
echo aplay "$1.wav" # remove echo to actually let aplay...
