Ok. So we have a sequence of chars (a -, then some digits you may want to use for exclusion, then a .) once and only once in each line. So here it is:

#!/bin/bash

inputfile="/tmp/buddyfile"
cp...

In this file "-94" and alike are not at the end of lines, as they were before. So no lines were excluded. You got 50% of 5 lines, so 2 lines (2.5 rounds to 2).

If you want a good excluding...

No, 25% is calculated on the remaining lines (after you excluded two lines).
So 25% of 2 is 0.5, which rounds to zero.

Try: ./program Myfile 50 50 52
You'll get 1 line randomly chosen among 2...

#!/bin/bash

inputfile="/tmp/buddyfile"
cp "$1" $inputfile
(( $# < 3 )) || {
string="-${3}$"
for ((a=4;a<=$#;a++)); do
string+="\|-${!a}$"
done

Another way, perhaps in other circumstances, could be to use named pipes. For instance:
$ mkfifo cmd1 cmd2
$ exec 2>/dev/null; echo -e "this\nthat" >cmd1 & echo -e "first\nsecond" >cmd2 & paste...

## Let's say that:
## the number of lines in your file is 200 (range=200);
## you want 30% of the lines in your file: percent=30.
## So we'll have that lim= 200 * 30 / 100 = 60.

Pardon? I'm sorry, but I don't know a word of German.
However Google translator helped me a bit, this time. :)

I thought it was your case, and that you didn't have any other directories at level...

Don't you have logrotate (or something alike) in your system?
What's wrong with it?

With sed, try this:
sed -n '/^$/b blk;H;$b blk;b;:blk;x;s/\n//;/PATTERN/!P' <file

Without escaping, the expression "s*.txt" matches a string that begins with zero or more s, goes on with another char no matter what (matched by the period), then goes on with txt. So it matches...

What about this different approach?
The example below is for 4 total instances, 2 of them run simultaneously.
i=0; while((i<=4)); do while (( $(pgrep -c myscript) < 2 )); do let i++ ; nohup...

And what about find? If you don't have file names with spaces or strage chars, please try:
#!/bin/sh
for arg in "$@"; do
date | tee -a $(find /var/lib -maxdepth 1 -name "$arg") >/dev/null ...

#!/bin/sh -e
cd /var/lib
for arg in $@; do
for file in /var/lib/$arg.dat; do
date >> $file
done
done

then call it this way:
sh -f -c "./dummy.sh a*"

I guess your problem can easily be solved with awk alone, but since I don't know awk... :(

A possible alternative solution can be this one: knowing which is the colums delimiter in your file (if...

If I'm right your problem is to randomly generate N integers in the range [1;M], where M is the number of lines in the file, and N is a rounded percentage of M.

Before going on: are repetitions...

Something like:
cut -d" " -f 4,6 --complement infile >outfile

Then check outfile. If it's fine, then:
mv outfile file

Uhm.
What's wrong with:
lem@biggy:/tmp$ while IFS="|" read -r T_NAME P_NAME P_CODE _PATH _DATE; do
cat <<END >>outfile
T_NAME $T_NAME
P_NAME $P_NAME
P_CODE $P_CODE
PATH $_PATH

This should work better:
sed 's/\.*0*\(~[^~]*\)$/\1/' <file

With sed:

Try starting from here:
#!/bin/ksh
while read line; do
read -A array <<<$line
n=${#array[@]}
echo "${array[0]} is my function"
for ((i=1;i<$n;i++)); do
print "${array[$i]} is datum"

sed -n '/^FAN/ s/.*\[\([^][]*\)\]$/\1/p' <file

From what I've been reading about those ShareSpace devices, there should be an LVM2 volume, indeed, on top of the raid. So you should find it, and then mount it. If things are like that, of course...

From mdadm man:


So you can --examine /dev/sdf4, for instance, not /dev/md2. And you can --detail /dev/md2, not /dev/sdf4. :)



Wait. We were speaking about a raid volume. This is for LVM(2)...
