cut

I am new to shell, I have a case where I am trying to evaluate a particular column unique values to check if they are valid in a shell script which will be invoked later. From my searches I think cut along with sort & unique is good to do it So my attempt is file=/filepath/*vendor.csv file_categories = `cut -d, -f1 $file |sort |unique` $file should hold file which has vendor in its filename but even after using command substitution (`) the $file is not getting replaced with the correct filename , it just places what is present in file Another example for what I am attempting is a=/stage

I am trying to make a script in bash that requires the removal of the the file extension from a file name, like the following original: something.zip removed version: something And I was thinking I could use cut for this, but I am worried that a situation could arise where there might be a file name that has more than one period, etc, something similar to the following something.v2.zip having said that, I was wondering if anyone had any recommendations as to what I could do to just remove the last period and the text after it from a line of text/filename? any help would be appreciated, thanks!

Is there any better methods to print two or more columns into one column, for example input.file AAA 111 BBB 222 CCC 333 output: AAA BBB CCC 111 222 333 I can only think of: cut -f1 input.file >output.file;cut -f2 input.file >>output.file But it's not good if there are many columns, or when I want to pipe the output to other commands like sort . Any other suggestions? Thank you very much! With awk awk '{if(maxc<NF)maxc=NF; for(i=1;i<=NF;i++){(a[i]!=""?a[i]=a[i]RS$i:a[i]=$i)} } END{ for(i=1;i<=maxc;i++)print a[i] }' input.file You can use a GNU awk array of arrays to store all the data and

I have trapped the cut event (jquery) on a textbox. What I want is to get the text on the textbox during the cut event is triggered. I've tried accessing the data the user cut via evt.originalEvent.clipboardData.getData('text') but returns undefined. My goal is to know if the user cut all the text (textbox is now empty) or not. Thanks in advance You can setTimeout with a duration of 0, which schedules a function for immediate execution. The nice thing is that the function will execute once the text has already been cut, so you can check then if your textarea is empty (which would mean that the
