awk

问题 I have a program that I can run in two ways: single-end or paired-end mode. Here's the syntax: program <output-directory-name> <input1> [input2] Where the output directory and at least one input is required. If I wanted to run this on three files, say, sample A, B, and C, I would use something like find with xargs or parallel: user@host:~/single$ ls sampleA.txt sampleB.txt sampleC.txt user@host:~/single$ find . -name "sample*" | xargs -i echo program {}-out {} program ./sampleA.txt-out .

问题 I've created an awk script and use it like this: # grep -E "[PM][IP][DO][:S]" file.txt | awk-script How can I modify the awk script to include the effort of the grep command (which is searching for either "PID:" or "MPOS"? awk-script is: #!/usr/bin/awk -f /Sleeve/ { printf("%8d, %7d, %7.2f, %7.2f, %7.2f\n", $5, $6, $7, $30, $31) } /Ambient/ { printf("%8d, %7d,,,, %7.2f, %7.2f\n", $5, $6, $7, $8) } /MPOS:/ { printf("%8d, %7d,,,,,, %5d, %5d\n", $4, $5, $2, $3) } 回答1: If you just want to search

问题 I have 2 files: file1 : 1,apple 2,mango 3,banana 44,orange file2 : 1,apple 22, 31,xyz 2,man 3,banana 44,oran 44,orange I need to find the differences from both the files using column 1 and checking column 2. I don't want to use $0 as its printing the lines which of 1st file which are not present in file2 too. Result output should be printed in file3 as : 2,mango,man 44,orange,oran Mango is from file1 (column 2) and man is from file2 (column2) 回答1: Slightly different awk: $ awk 'BEGIN{FS=OFS="

问题 can anybody teach me how to calculate the average for between the difference of time? for example 412.00 560.00 0 0 361.00 455.00 561.00 0 0 0 0 0 0 237.00 581.00 425.00 464.00 426.00 520.00 0 0 the normal case, they do the sum of all of those number divide by total set of number sum/NR the challenge here the number of column is dynamic, which mean not all of the line have the same number column to calculate the average , example we have this : 361.00 455.00 561.00 so the calculation : ((455

问题 I am trying to write an awk script and before anything is done tell the user how many lines are in the file. I know how to do this in the END section but unable to do so in the BEGIN section. I have searched SE and Google but have only found a half dozen ways to do this in the END section or as part of a bash script, not how to do it before any processing has taken place at all. I was hoping for something like the following: #!/usr/bin/awk -f BEGIN{ print "There are a total of " **TOTAL LINES

问题 I have a file ( filename.txt ) with the following structure: >line1 ABC >line2 DEF >line3 GHI >line4 JKL I would like to shuffle the characters in the strings that do not start wit > . The output would (for example) look like the following: >line1 BCA >line2 DFE >line3 IHG >line4 KLJ This is what I tried to shuffle the characters in a string: sed 's/./&\n/' | shuf | tr -d "\n" . It looks like it works but it does not take into account newlines. Moreover it executes the command on all data and

问题 Trying to merge some data that I have. The input would look like so: foo bar foo baz boo abc def abc ghi And I would like the output to look like: foo bar baz boo abc def ghi I have some ideas using some arrays in a shell script, but I was looking for a more elegant or quicker solution. 回答1: How about join? file="file" join -a1 -a2 <(sort "$file" | sed -n 1~2p) <(sort "$file" | sed -n 2~2p) The seds there are just splitting the file on odd and even lines 回答2: While pixelbeat's answer works, I
