I need to add timestamp to the beginning of each line printed in the following output.
# top -b |grep -w 'db2sysc\|java'
4756 db2inst1 20 0 2525m 875m 830m S 0 11.0 1:33.57 db2sysc
4951 root 20 0 1416m 689m 7276 S 0 8.7 1:27.86 java
4756 db2inst1 20 0 2525m 875m 830m S 1 11.0 1:33.61 db2sysc
4951 root 20 0 1416m 689m 7276 S 0 8.7 1:27.87 java
would like it like this
1366138603 4756 db2inst1 20 0 2525m 875m 830m S 0 11.0 1:33.57 db2sysc
1366138603 4951 root 20 0 1416m 689m 7276 S 0 8.7 1:27.86 java
1366138692 4756 db2inst1 20 0 2525m 875m 830m S 1 11.0 1:33.61 db2sysc
1366138692 4951 root 20 0 1416m 689m 7276 S 0 8.7 1:27.87 java
Thank you for any help.
I'd suggest using awk instead of grep:
top -b | awk '/db2sysc|java/ {print systime(), $0}'

I have a simple docker container that is based on windows image:
FROM mcr.microsoft.com/windows:1903
WORKDIR /app1/
ENTRYPOINT powershell.exe
I run it interactively, using:
docker run -it -v c:\app1:c:\app1 test-image:1.0
There is a file called 1.txt inside app1 folder.
When I run:
.\app1\1.txt
I see no notepad.exe process, but instead I can spot OpenWith process:

I suspect that some mapping might be missing, event though assoc shows that .txt file is associated with notepad.exe:
assoc .txt
.txt=txtfile
ftype txtfile
txtfile=%SystemRoot%\system32\NOTEPAD.EXE %1
What might be the problem here? Am I missing some register value?
The command '(sleep 4 ; echo q) | topas -P |tee /tmp/top' on AIX produces this output in a command text file and I am not able to remove the blank spaces from it. I have tried, sed/perl and awk commands to print only the lines containing characters however nothing has helped. Do I need to convert this file to a ASCII text format to use sed/per/grep or awk to remove the empty lines?.
$ file /tmp/top
/tmp/top: commands text

Looks like your output file has some ASCII characters so it's better to print only those lines which starting from letters do like:
awk '/^[a-zA-Z]/' Input_file
How to delete lines that do not match the pattern except the first line?
To delete lines except first i use
sed '1!d'
To delete lines that do not match patter i use
sed '/pattern/!d'
How can i use both of conditions? Things like
sed '1!/pattern/!d'
doesn't work, says unknown command: '/'
As example (if pattern="rcu")
from input

4 2 39 -20 0 0 I< 00:00:00 [rcu_par_gp]
Thanks
Output first line and all lines which contain rcu:
sed -n '1p; /rcu/p' file
You could also make a script that reads the file and “extracts” first line that don’t match the pattern (to another temporary file or to the string), make other operations like deleting lines that you want to be deleted and paste that line back in the same place in the file.
As you have tagged awk
awk '{if ($0~/rcu/) print}'
Demo :
$ cat file1.txt
PID PPID PRI NI VSZ RSS STAT TIME CMD
1 0 19 0 33664 4832 Ss 00:00:07 /sbin/init splash
2 0 19 0 0 0 S 00:00:00 [kthreadd]

4 2 39 -20 0 0 I< 00:00:00 [rcu_par_gp]
8 2 39 -20 0 0 I< 00:00:00 [mm_percpu_wq]
9 2 19 0 0 0 S 00:00:04 [ksoftirqd/0]
$ awk '{if ($0~/rcu/) print}' file1.txt
3 2 39 -20 0 0 I< 00:00:00 [rcu_gp]
4 2 39 -20 0 0 I< 00:00:00 [rcu_par_gp]
$
If when you say except the first if you mean except the first line of the input even if it doesn't match the regexp then this is what you want:
$ awk '/rcu/ || NR==1' file
PID PPID PRI NI VSZ RSS STAT TIME CMD
3 2 39 -20 0 0 I< 00:00:00 [rcu_gp]
4 2 39 -20 0 0 I< 00:00:00 [rcu_par_gp]
or if you mean except the first line that doesn't match the regexp then this is what you want:
$ awk '/rcu/ || !c++' file
PID PPID PRI NI VSZ RSS STAT TIME CMD
3 2 39 -20 0 0 I< 00:00:00 [rcu_gp]

I've installed Cygwin v3.1.2 (0.340/5/3) and ConEmu v20191012 (64bits)
When I run the command line below
c:\temp>ls -ls
total 0
0 -rw-rw-r--+ 1 me None 0 Jan 5 12:40 fileA
0 -rw-rw-r--+ 1 me None 0 Jan 5 12:40 fileB
0 -rw-rw-r--+ 1 me None 0 Jan 5 12:40 fileC
I don't get the directory items aligned. But if I perform same action on another computer with Cygwin 2.11.1 (0.329/5/3) and ConEmu v20191012 (64bits), I'll get the expected result, as it's shown next:
$ ls -ls
total 0
0 -rwxrwx---+ 1 me UK+Group(513) 0 Jan 5 12:41 fileA
0 -rwxrwx---+ 1 me UK+Group(513) 0 Jan 5 12:41 fileB
0 -rwxrwx---+ 1 me UL+Group(513) 0 Jan 5 12:41 fileC
Any idea about how to solve this problem?
Thanks!
Once I've downloaded CyWwin 3.1.7, the issue does not exist anymore.
Thanks!
I'm running a validation software and I want all of the output sent to a text file and have the results of multiple files placed/appended to the same file. I thought my code was working, but I just discovered I'm only getting the results from 1 file output to the text file.
java -jar /Applications/epubcheck-3.0.1/epubcheck-3.0.1.jar ~/Desktop/Validator/*.epub 2>&1 | tee -a ~/Desktop/Validator/EPUBCHECK3_results.txt
open ~/Desktop/Validator/EPUBCHECK3_results.txt
EDIT
When I run the same .jar file using Windows command line it will process a batch of files and appeand the results appropriately. I would just do this, but it would mean having to switch work stations and transferring files to validate them. I would like to get this running through the Unix shell on my Mac system so that I don't have to do unnecessary work. Command line that IS working below:
FOR /f %%1 in ('dir /b "C:\Users\scrawfo\Desktop\epubcheck\drop epubs here\*.epub"') do (
echo %%1 >> epubcheck.txt
java -jar "C:\Users\scrawfo\Desktop\epubcheck\epubcheck-3.0.jar" "C:\Users\scrawfo\Desktop\epubcheck\drop epubs here\%%1" 2>> epubcheck.txt
echo. >> epubcheck.txt)
notepad epubcheck.txt
del epubcheck.txt
syntax provided by you is correct there might be some problem with java output or something Try Executing it without redirection
