[SOLVED] How to make Array into string in AWK and split

Andy_Crowd · 05-16-2016, 11:25 AM

Hello!

I need all part of array get as an string, split and show new with separated parts.

Code:

grep ^Categories -h -R /usr/share/applications/ | awk -F= '//{
A[C++]=$2
}END{
B=A[@];
split(B,D,";");
for( I in D)print D[I];
}'

Thanks for any help!

It might help if you post some sample data. Also, grep is redundant if you have awk. Try / /

Code:

awk '/somepattern/ { someactions }' somefile

Yes, I was just about to say that. I would add: post what you expect to see as output. Then the problem should be trivial.

To expand on the previous post by Turbocapitalist ...
Help us to help you. Provide a sample input file (10-15 lines will do). Construct a sample output file which corresponds to your sample input and post both samples here. With "Before and After" examples we can better understand your needs and also judge if our proposed solution fills those needs.

Here is a simply explanation as I want make it work in awk:

Code:

A=A+B[I]

split(A,C,";")

***loop***
print C[II]
**********

This is working script. If it will be possible to have all in the same variable then I could skip using "sort -u"

Code:

grep ^Categories -h -R "/usr/share/applications/" "$HOME/.local/share/applications/" | \
awk -F= '//{A[$2]=1
}END{
for(E in A){gsub(";","\n",E);printf E}
}' | sort -u

I solved it! Pretty simply but I couldn't give correct question to get right answer. Sometimes it just coming as an apple on head under tree.

Code:

grep ^Categories -h -R "/usr/share/applications/" | \ 
awk -F= '//{
 A[$2]=1
}END{
 for(E in A)ZZ=ZZ E;
 split(ZZ,YY,";");
 asort(YY);
for(I in YY)
 HH[YY[I]];
for(QQ in HH)
 print QQ}'

Thank you for your support and your time!!!

Guess we will have to take your word for it seeing as you did not want any of our help ... not really sure why you asked the question in the first place.

I didn't know how to do it. I tested A=A+Array[I], A+=Array[I], A[Array[I]] and even split(Array,B,";") but got bad results and I wanted to split into a new array after I collected all in a same variable. I got really lost, I am still a newbie to use "awk". After I asking questions I still continue to look around if it is not a really complex, but sometimes even simple things can be complex. I found out that in awk it works a little different, to add a variable to another for splitting is: "A=A Array[I]", I isn't necessary to use + as I thought, impossible to split in whole array, it is just enough to use space between variables.

Well I am glad you found a solution, it may not be the most expedient and you have not given anyone here a chance to show you an alternative because you refuse to answer any of the questions asked
of you. No one is knocking you learning, but your question was made moot by the fact you would not tell anyone the information requested ... which is why I thought it was kind of a waste
to ask the question in the first place if you didn't really want help.

Hopefully your future endeavours will come to you as well

Good luck
