I was looking for a single one-liner to produce a line with all data:
These four [separate] commands produce the info I need, but I don't know how to concatenate them into a single line:
$ cat /proc/cpuinfo | grep "model name" | sed -n -e 's/^.*: //p'
ARMv6-compatible processor rev 7 (v6l)
$ lscpu | grep "CPU(s):" | awk '{print $2}'
1
$ lscpu | grep "CPU min MHz:" | awk '{print $4}'
700.0000
$ lscpu | grep "CPU max MHz:" | awk '{print $4}'
1000.0000
And I wanted to get:
ARMv6-compatible processor rev 7 (v6l) x1 #700 MHz (max #1000 MHz)
just using echo
echo $(cat /proc/cpuinfo | grep "model name" | sed -n -e 's/^.*: //p') \
x$(lscpu | grep "CPU(s):" | awk '{print $2}') \
#$(lscpu | grep "CPU min MHz:" | awk '{print $4}') \
'( max' $(lscpu | grep "CPU max MHz:" | awk '{print $4}') ')'
By the way, you could use just grep "model name" /proc/cpuinfo instead of cat /proc/cpuinfo | grep "model name"
One way.
paste -d ' ' <(awk '/^model name/{sub(/.+: /,"");print;exit}' /proc/cpuinfo) <(lscpu | awk '/CPU min MHz:/{printf " (max #%d MHz) ", $4} /CPU max MHz:/{printf "#%d MHz", $4} /^CPU\(s\):/{printf "x%s ", $2}')

I need to put the first APEC of first as First PID, third line of APEC and Second PID and last one as Third PID.
I've tried awk but no expected result.
> First_PID =ps -ef | grep [j]ava | awk '{print $2,$9}'|awk '{if ($0 == "[^0-9]" || $1 == "APEC:") {print $0; exit;}}'
Expected result should look like this.
> First_PID=45134
> Second_PID=45136
> Third_PID=45135
With your shown samples and attempts please try following awk code. Written and tested in GNU awk.
ps -ef | grep [j]ava |
awk '
{
val=$2 OFS $9
match(val,/([0-9]+) -Dapex=APEC ([0-9]+) -Dapex=JAAA\s([0-9]+)/,arr)
print "First_PID="arr[1],"Second_PID=",arr[3],"Third_PID=",arr[2]
}
'
How about this:
$ input=("1 APEC" "2 JAAA" "3 APEC")
$ printf '%s\n' "${input[#]}" | grep APEC | sed -n '2p'
3 APEC
Explanation:
input=(...) - input data in an array, for testing
printf '%s\n' "${input[#]}" - print input array, one element per line
grep APEC - keep lines containing APEC only
sed -n - run sed without automatic print
sed -n '2p' - print only the second line
If you just want the APECs first...
ps -ef |
awk '/java[ ].* -Dapex=APEC/{print $2" "$9; next; }
/java[ ]/{non[NR]=$2" "$9}
END{ for (rec in non) print non[rec] }'
If possible, use an array instead of those ordinally named vars.
mapfile -t pids < <( ps -ef | awk '/java[ ].* -Dapex=APEC/{print $2; next; }
/java[ ]/{non[NR]=$2} END{ for (rec in non) print non[rec] }' )
After read from everyone idea,I end up with the very simple solution.
FIRST_PID=$(ps -ef | grep APEC | grep -v grep | awk '{print $2}'| sed -n '1p')
SECOND_PID=$(ps -ef | grep APEC | grep -v grep | awk '{print $2}'| sed -n '2p')
JAWS_PID=$(ps -ef | grep JAAA | grep -v grep | awk '{print $2}')
I'm got this working:
while sleep 5s
do
lscpu | grep 'CPU MHz:' | cut -d ':' -f 2 | awk '{$1=$1};1' && grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'
done
And it gives me the following output:
1601.058
3.4811%
1452.514
3.48059%
1993.800
3.48006%
2085.585
3.47955%
2757.776
3.47902%
1370.237
3.47851%
1497.903
3.47798%
But I'd really like to get the two values onto a single line. Every time I try to do this I run into a double / single quote variable issue. Granted I pulled some of this awk stuff from online so I'm not really up to speed on that. I just want to print per line, CPU clock and load ever 5 seconds.
Can you help me find a better way to do that?
You may use process substitution to run lscpu and cat /proc/stat and feed to single command. No need to use pipes.
while sleep 5; do
awk '/CPU MHz:/{printf "%s ", $NF} /cpu /{print ($2+$4)*100/($2+$4+$5)"%"}' <(lscpu) /proc/stat
done
If there is only one input command:
date| awk '{print $1}'
Wed
OR
awk '{print $NF}' <(date)
2019
If more then one command: Example , get the year of of the two date command in same line. (not very useful example, only for sake of demo)
awk '{printf "%s ", $1=NF}END{print ""}' <(date) <(date)
2019 2019
pipe the output of the 2 commands into paste
while sleep 5; do
lscpu | awk -F':[[:blank:]]+' '$1 == "CPU MHz" {print $2}'
awk '$1 == "cpu" {printf "%.4f%%\n", ($2+$4)*100/($2+$4+$5)}' /proc/stat
done | paste - -
The 2 columns will be separated by a tab.
Writing this for readability rather than efficiency, you might consider something like:
while sleep 5; do
cpu_pct=$(lscpu | awk -F': +' '/CPU MHz:/ { print $2 }')
usage=$(awk '/cpu / {usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}' /proc/stat)
printf '%s\n' "$cpu_pct $usage"
done
Command substitutions implicitly trim trailing newlines, so if lscpu | awk has output that ends in a newline, var=$(lscpu | awk) removes it; thereafter, you can use "$var" without that newline showing up.
All you need to do is change the newline on the first line to a different separator. Something like:
lscpu | ... | tr \\n : && grep ...
You can also use echo -n $(command_with_stdout). The -n switch specifies that the new line (\n) will be omitted.
while sleep 5s; do
echo -n $( lscpu | grep 'CPU MHz:' | cut -d ':' -f 2 | awk '{$1=$1};1' )
echo -n ' **** '
echo $( grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}' )
done
Or the same representation in one line:
while sleep 5s; do echo -n $( lscpu | grep 'CPU MHz:' | cut -d ':' -f 2 | awk '{$1=$1};1' ); echo -n ' **** '; echo $( grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}' ); done
EDIT: (remove -n switch from echo according to Charles Duffy's comment)
while sleep 5s; do echo "$( lscpu | grep 'CPU MHz:' | cut -d ':' -f 2 | awk '{$1=$1};1' ) **** $( grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}' )"; done
This gives me the duplicates and the number of times it is repeated
$ awk -F "\"*,\"*" '{print $2}' file.csv | sort | uniq -c | sort -nr | head -n 2
4 12345
3 56789
What I then want to do is add the first column (3+4). I can do this if i write the output above to a file test. I can do this as follows:
$ awk -F" " '{print $1}' test
4
3
$ awk -F" " '{print $1}' test | paste -sd+
4+3
$ awk -F" " '{print $1}' test | paste -sd+ | bc
7
But I want to be able to do this in 1 line, and ideally don't want to write to a file, would like to understand why the following does not work
awk -F "\"*,\"*" '{print $2}' file.csv | sort | uniq -c | sort -nr | head -n 2 | awk -F" " '{print $1}' | paste -sd+ | bc
My 2nd awk seems to not like the input.
Can anyone advise how I do this, and what I am doing wrong?
EDIT1 - file.csv looks like:
"Date","Number"
"2015-11-01","12345"
"2015-11-01","12345"
"2015-11-01","12345"
"2015-11-01","12345"
"2015-11-01","56789"
"2015-11-01","56789"
"2015-11-01","56789"
awk to the rescue!
... | sort -nr | awk 'NR<=2{sum+=$1} END{print sum}'
you can pick the first two rows and summation in awk as well.
Below is my code. But bash is doing word splitting therefore I have failure. How to make my script so that there is no word splitting.
namaSensor=$(sensors | egrep "°C" | awk '{print $0}' | awk -F ':' '{print $1}')
for sensor in $namaSensor
do
if [ $(sensors | grep -c "$sensor") -ne 0 ]
then
currentTemperature=$(sensors | egrep "$sensor" | awk '{print $0}' | awk -F '+' '{print $2}' | cut -c 1-4 | awk -F '.' '{print $1}')
maxTemperature=$(sensors | egrep "$sensor" | awk '{print $0}' | awk -F '+' '{print $3}' | cut -c 1-4 | awk -F '.' '{print $1}')
if [ $currentTemperature -lt $maxTemperature ]
then
printf "current temperature is %d°C and the maximum allowed temperature is %d°C\n" "$currentTemperature" "$maxTemperature"
printf "temperature is within the maximum allowed temperature\n"
echo "$sensor"
else
printf "current temperature is %d°C and the maximum allowed temperature is %d°C\n" "$currentTemperature" "$maxTemperature"
printf "temperature is more than the maximum allowed temperature\n"
#exit 255

done.
This is the output of sensors for my unit.

Please help
As I understand you have your array splitted as following:
Physical
id
0
and so on. To change this behaviour you need to change your Internal Field Separator (IFS) to a newline. So your code should look like this:
IFS=$'\n'
nameSensor=$(sensors | egrep "°C" | awk '{print $0}' | awk -F ':' '{print $1}')
for sensor in $nameSensor
do
if [ $(sensors | grep -c "$sensor") -ne 0 ]; then
currentTemperature=$(sensors | egrep "$sensor" | awk '{print $0}' | awk -F '+' '{print $2}' | cut -c 1-4 | awk -F '.' '{print $1}')
maxTemperature=$(sensors | egrep "$sensor" | awk '{print $0}' | awk -F '+' '{print $3}' | cut -c 1-4 | awk -F '.' '{print $1}')
if [ $currentTemperature -lt $maxTemperature ]; then
printf "current temperature is %d°C and the maximum allowed temperature is %d°C\n" "$currentTemperature" "$maxTemperature"
printf "temperature is within the maximum allowed temperature\n"
echo "$sensor"
else
printf "current temperature is %d°C and the maximum allowed temperature is %d°C\n" "$currentTemperature" "$maxTemperature"
printf "temperature is more than the maximum allowed temperature\n"
#exit 255

Is there a way to hide xfce4-panel from command line. If no any other solutions how to hide it from terminal ?
Regards,
Levon
I got here wondering the same. Apparently there is no direct command, but it's pretty straightforward to write a shell script:
INFO=$(xwininfo -name xfce4-panel)
STATE=$(echo "$INFO" | grep "Map State:" | head -n1 | awk -F: '{print $2}' | xargs)
WID=$(echo "$INFO" | grep "Window id:" | head -n1 | awk -F: '{print $3}' | awk '{print $1}')
if test "$STATE" = "IsViewable"; then
xdotool windowminimize "$WID"
else
xdotool windowmap "$WID"
