问题 I have a requirement as below 121.36 121.025 121.1 121.000 Desired output 122 122 122 121 Command used awk -F"." '{if($8>0){print $11}}' 回答1: What you're asking for is a ceil() (for "ceiling") function. It's important to include zero and negative numbers in your example when you're looking for any kind of rounding function as it's easy to get them wrong so using this input file: $ cat file 1.999999 1.0 0.000001 0 -0.000001 -1.0 -1.999999 we can test a ceil() function: $ awk 'function ceil(x,

问题 I am trying to interweave two files that contain one sentence per line. I double spaced ( sed G ) the first file and I would like to incorporate the content of the second file into those empty lines. How can I interweave both files so that the 1st line of file B goes below the 1st line in file A, the 2nd line of file B below the 2nd line of file A, until it reaches the end ? Example: [line number|sentence number|sentence] 1 1 fileA 2 3 2 fileA 4 5 3 fileA 6 7 4 fileA Expected result: 1 1

问题 I have file with data cell input out type fun level AI20 A1,A2 Z comb ((A1A2)) 2 IA2 A1,A2,A3 Z comb ((!A1A2)A3) 3 XOR A1,A2,B1 Z comb (((A1A2)B1) 3 IAD A1,A2,A3 Z comb (!((A1A2)A3)) 3 INV I1 ZN comb (!I1) 1 BUF A1,A2,A3,B1 Z comb (!(((A1A2)A3)B1)) 4 From this data, I want to print rows whose level field (6th column) gives sum 7 together. here to get level sum 7 we can select AI2O , BUF , INV rows giving level sum as 2 + 4 + 1 = 7 and print them Or can select XOR , IAD , INV giving sum 3 + 3

问题 I want to split a text file like the one pasted below (sorry for the length), on every n occurence of ">". For example, every 2nd occurrence of ">", but I need to able able to change that number. test_split.txt: >eeefkdfn a a a >c 4ufjdhf b b b b > c c > c d d d d d >3 >cr >c3 e e e e e > 5 f f f f >cr g g g g > cr dkjfddf h h h h So I want to have output files this these (only showing the first two): file_1.txt: >eeefkdfn a a a >c 4ufjdhf b b b b file_2.txt: > c c > c d d d d d etc. Question

问题 Strongly typed regexp constants is a handy tool that GNU Awk has. It is documented in GNU Awk User's Guide -> 6.1.2.2 Strongly Typed Regexp Constants and in there you can find interesting examples. From reading it, and comments to an answer I made up some examples that show those: $ cat file he;llo ho are you; $ gawk -v patt='@/;/' '$0 ~ patt' file # it prints those lines containing ";" he;llo you; In this case, we pass the pattern ";" with @/;/ and so it prints all the lines that contain ";"
