In Cygwin, I can get the list of running processes by following command:
PID PPID PGID WINPID TTY UID STIME COMMAND
13160 1 13160 13160 ? 197609 13:42:18 /usr/bin/mintty
S 15404 2852 15404 16776 pty2 197609 13:59:29 /usr/bin/vi
2852 12912 2852 11244 pty2 197609 13:42:54 /usr/bin/bash
9864 1 9864 9864 ? 197609 13:11:32 /usr/bin/mintty
S 10500 2852 1692 1452 pty2 197609 14:09:42 /usr/bin/less
S 17644 2852 17644 11880 pty2 197609 14:00:15 /usr/bin/vi
12912 1 12912 12912 ? 197609 13:42:54 /usr/bin/mintty
8432 2852 8432 12020 pty2 197609 14:10:05 /usr/bin/ps
17092 13160 17092 14720 pty1 197609 13:42:18 /usr/bin/bash
However, I just want the COMMAND column but not all columns like this:
COMMAND
/usr/bin/mintty
/usr/bin/vi
/usr/bin/bash
/usr/bin/mintty
/usr/bin/less
/usr/bin/vi
/usr/bin/mintty
/usr/bin/ps
/usr/bin/bash
In MAC, I can do this by the following command:
ps -o command
The same command is not working for cygwin in windows because the -o option is not there in ps for cygwin.
you can use awk to print only the selected column.
$ ps |awk '{ if (NF==8) {print $8} else {print $9}}'
COMMAND
/usr/bin/ps
/usr/bin/bash
/usr/bin/mintty

I have an file , my file name is lookup.txt. Sometimes this file content is 100 lines , so everything scroll while printing. Thats why i like to print it on screen in 2 or more columns.
my bash doesnt support commands like pr or columns.Need to be in old fashion shell.
Content of lookup file is:
1-Top Scores
2-Last Scores
3-Username
4-Birthday
5-Last Meal today
6-Coronavirus in Italy
7-Lets Stay Home
8-Winner
9-Germany and Belgium
10-Alfa
11-Bravo
12-Charlie and delta
For printing in columns i use this command found here on stackoverflow:
cat lookup.txt | xargs printf '%-24s\n' | sed '$p;N;s/\n//;$p;N;s/\n//'
and this is the print in columns:
1-Top Scores 2-Last
Scores 3-Username 4-Birthday
5-Last Meal today
6-Coronavirus in Italy
7-Lets Stay Home
8-Winner 9-Germany and
Belgium 10-Alfa 11-Bravo
12-Charlie and delta
What i need is to let sed not split the words into different columns but just the line.
1-Top Scores 6-Coronavirus in Italy 11-Bravo
2-Last Scores 7-Lets Stay Home 12-Charlie and delta
3-Username 8-Winner
4-Birthday 9-Germany and Belgium
5-Last Meal today 10-Alfa
if the 3 columns are to width then x chars then print in 2 columns (this last is optional)
thanks in advance

Not claiming complete credit, you can modify this andlrc's answer on In bash how can I split a column in several column of fixed dimension to your requirement.
Instead of appending the columns with a whitespace, you can use sprintf() to custom print your column strings. Tested on GNU awk
awk '
BEGIN {
# Numbers of rows to print
n=5;
}
{
# Add to array with key = 0, 1, 2, 3, 4, 0, 1, 2, ..
l[(NR-1)%n] = sprintf("%s%-24s", l[(NR-1)%n], $0)
};
END {
# print the array
for (i = 0; i < length(l); i++) {
print l[i];
}
}
' file
Try this:
cat lookup.txt | tr '\n' '\0' | xargs -0 -n 2 printf '%-24s %-24s\n'
The tr command will convert newlines to nul chars.
Then we tell xargs to take nul-separated args and pass two at a time to the command.
I need to kill a windows procces that were started by the programm called from cygwin.
Here's what I do:

How can i kill them?
I tried to kill them by the following command:
ps -W | grep "WCC" | awk '{print $1}' | xargs kill -f;
But it does not work as it should, it kills all processes in which name there are letters WCС, and I need to terminate only the child processes of WCCILpmon.exe
I also read the question on cygwinlist about same problem
And it upset me, is there no way to realize it?
As you need to kill a NOT cygwin process, it is better to use
windows specific program.
One example is:
https://learn.microsoft.com/en-us/sysinternals/downloads/pskill
i'm trying to build a small script that cut only the file names i want and move them to another mos file.
when the grep is executing i get the error (look down the code)

pls enter RBS number eg LTE8824,: LTE1976

if i'll take only this line:

can someone tell me why i get this error while i'm scripting and while i'm running the cmd as he is it's OK?
I have a tar/gzip file I am extracting to a list of hosts using the ansible unarchive module.

I've tried various iterations of the "exclude" option, including
exclude='[ ".mutt" ]'
exclude='[ ".mutt", ".mutt/*" ]'
These appear to work, but I always end up with the entire contents of the .mutt directory being extracted.
Where am I going wrong?
Per the comments, there is a bug logged for this issue.
The work-around is to use a YAML list for the exclusions and to make sure the list exactly matches the path/file stored in the archive.
vars:
exclusions:
- ./.mutt
and
unarchive: src=configs/configs.tgz dest=/tmp/a exclude={{ exclusions }}
I have a BASH/shell script, running on Linux, but it sometimes has a problem getting the drive labels, using blkid.. blkid gets the drive labels nad UUIDs of the given drive.
Example of blkid output:
# blkid /dev/sda1
/dev/sda1: LABEL="Home" UUID="f1e5e82b-1c75-4fd7-8841-6ad766152dcf" TYPE="ext2"
The problem occurs when the drive label has a newline character... I have included the relevant function. The problem seems to be with the eval command.. Can someone help me?
blkid_name_generator() {
#Gather blkid output and filter out required device
if [ ! -f /tmp/blkid.txt ]; then
blkid -c /dev/null > /tmp/blkid.txt
fi
blkid_cleaner &
LABEL=""
LABEL1=""
eval $( cat /tmp/blkid.txt | grep "$#:" | cut --delimiter=" " -f 2- | sed -e 's/ /;/g')
LABEL1=${LABEL//;/ } # akita beta4 fix: remove newlines below
LABEL=`echo $LABEL1 | tr -d '\n'` # akita beta5 fix, remove newlines from drive label
#Generate drive label
[ "$LABEL" = "" ] && ONEDRVLABEL="$#\n \n " || ONEDRVLABEL="${LABEL}\n($#)\n "
echo "${LABEL}" and "${ONEDRVLABEL}"
}
blkid_name_generator /dev/sda1
Here's my bash snippet:
while read curline; do
if [[ ${curline:0:1} == "/" ]]; then
[[ $prevline ]] && echo "$prevline"
prevline="$curline"
else
prevline+="$curline"
fi
done < $INPUTFILE
[[ $prevline ]] && echo "$prevline"
Here's my test file:
/dev/sda1: LABEL="Boot" UUID="fdc5e51d-3da6-4edf-bf07-6397b1765797" TYPE="ext2"
/dev/sda2: LABEL="Root" UUID="f883df24-1b93-46fb-8990-840774c380c4" TYPE="ext4"

/dev/sda2: LABEL="Root" UUID="f883df24-1b93-46fb-8990-840774c380c4" TYPE="ext4"
Here's my test file after processed by the bash snippet:
/dev/sda1: LABEL="Boot" UUID="fdc5e51d-3da6-4edf-bf07-6397b1765797" TYPE="ext2"

Hope this helps!
I don't see exactly what your script is intending to do (apart from the missing bits).
Here's what I came up with:
blkid | perl -ne 'print "$1\n" if m/LABEL="(.*?)"/o'
It will show this (on my system):
test^J123
WIN7VIRT
TEMP
Note how the newline in the label is depicted as ^J ? Viewing through a hex encoder shows that it is indeed a two-character combination 0x5e 0x4a
Hope you can get some further with that.
PS: 'proof' that the newline is in fact correctly in the volume label
tune2fs /dev/sdc1 -l

Thanks to this question... I could find a solution for another problem. Example (sda2 = ntfs partition):
blkid /dev/sda2
Segmentation Fault (core dump)
Hard to find troubleshooting guide for this issue (ubuntu based OS or any other)
The reason behind is a malformed LABEL in NTFS partition.
(of course, mal-formation we cant see, as newlines ;-)
Solution: Clear LABEL with GParted; then rewrite it or set a new LABEL.
