sh

Hi I'm looking to search through a file and output the values of a line that matches the following regex with the matching text removed, I don't need it output to a file. This is what I am currently using and it is outputting the required text but multiple times: #!/bin/sh for file in *; do sed -e 's/^owner //g;p;!d ; s/^admin //g;p;!d ; s/^loc //g;p;!d ; s/^ser //g;p;!d' $file done The preferred format would be something like this so I could have control over what happens inbetween: for file in *; do sed 's/^owner //g;p' $file | head -1 sed 's/^admin //g;p' $file | head -1 sed '/^loc //g;p'

I want to add a trailing argument to the appending version of the -exec option of find . find . -exec echo {} asd + # expecting the following output: file1 file2 file3 [...] asd Does not work as {} must be the last word before + . (Bonus question: Why was that trivial looking feature not implemented?) What is the simplest expression to archive this, that can handle filenames with spaces and special characters? POSIX conformance would be a nice to have but it is sufficient if it works with Linux. find . -exec sh -c 'echo "$@" asd' _ {} + 来源： https://stackoverflow.com/questions/40429954/trailing

I am trying to do the following in sh. Here's my file: foo bar Tests run: 729, Failures: 0, Errors: 253, Skipped: 0 baz How can I pull the 4 numbers into 4 different variables? I've spent about an hour now on sed and awk man pages and I'm spinning my wheels. Adopting my prior answer to use the heredoc approach suggested by @chepner: read run failures errors skipped <<EOF $(grep -E '^Tests run: ' <file.in | tr -d -C '[:digit:][:space:]') EOF echo "Tests run: $run" echo "Failures: $failures" echo "Errors: $errors" echo "Skipped: $skipped" Alternately (put this into a shell function to avoid

I am reading a .properties file from my shell script. I wanted to read some value for some key and after that want to append it in between some string but the output is weird. #!/bin/bash # Script used to read Property File FILE_NAME="Test.properties" prop_value=$(cat ${FILE_NAME} | grep Address) echo "ABC${prop_value}DEF" my Test.properties is like this Name=Pravin Age=25 Address=Mumbai asd=asd After executing this script I am expecting ABCAddress=MumbaiDEF but I am getting output like DEFAddress=Mumbai What would be the problem here? If I define any variable in a script it works, but when I

Consider this tiny text file: ab a If we run it through sort(1), we get a ab because of course a comes before ab . But now consider this file: ab|c a|c If we run it through sort -t'|' , we again expect a to sort before ab , but it does not! (Try it under your version of Unix and see.) What I think is happening here is that the -t option to sort is not really delimiting fields -- it may be changing the way (say) the start of field 2 would be found, but it's not changing the way field 1 ends . a|c sorts after ab|c because '|' comes after 'b' in ASCII. (It's as if the -t'|' argument is ignored,

I've got a program that I want to call by passing parameters from a shell variable. Throughout this question, I am going to assume that it is given by #!/bin/sh echo $# i.e. that it prints out the number of arguments that are passed to it. Let's call it count-args . I call my program like this: X="arg1 arg2" count-args $X This works quite well. But now one of my arguments has a whitespace in it and I can't find a way to escape it, e.g. the following things do not work: X="Hello\ World" X="Hello\\ World" X="'Hello World'" In all of the cases, my program count-args prints out 2 . I want to find
