Splitting script with getops bash script -


i'm trying split code using options getops, i'd 1 script run if 1 option set, , script run if option set, see code:

#!/bin/bash  # posix variable optind=1         # reset in case getopts has been used in shell.  # initialize our own variables: 1="" 2="" verbose=0   while getopts "h?v:f:m:l:" opt;     case "$opt" in     h|\?)         exit 0         ;;     v)  verbose=1         ;;     f)  1=$optarg         ;;     m)  2=$optarg         ;;     esac done  file in $1;         1="$(sed '1d' $1 | awk -f \" '{print $2}')"         printf "$1\n" done <"$1"  file in $2;         2="$(awk '{print $1}' $2 | sort | uniq)"         printf "$2\n" done <"$2"

so in code here, if option -f set file, i'd loop starting "for file in $1" run. , if -m set file, i'd loop starting "for file in $2" run.

i'd make -m or -f can run, i.e. not @ same time.

the command-line usage is: ./script.sh -f file.txt or ./script.sh -m file.txt

how can set this? (accepting other options other getops too)

example file -f:

<blank line> "b2f5ff47436671b6e533d8dc3614845d","54fd1711209fb1c0781092374132c66e79e2241b","path/path","output" "8fa14cdd754f91cc6554c9e71929cce7","4a0a19218e082a343a1b17e5333409af9d98f0f5","path/path2","output2" "2510c39011c5be704182423e3a695e91","27d5482eebd075de44389774fce28c69f45c8a75","path/path3","output3" ...

example file -m:

b2f5ff47436671b6e533d8dc3614845d /paths/path 2510c39011c5be704182423e3a695e91 /paths/path2

i'm using awk pull out first field -f , -m file. sed command removes first line () of file before extracts first field out.

expected output:

b2f5ff47436671b6e533d8dc3614845d 8fa14cdd754f91cc6554c9e71929cce7 2510c39011c5be704182423e3a695e91 b2f5ff47436671b6e533d8dc3614845d 2510c39011c5be704182423e3a695e91

which can use match against hashlist file.

assuming contents of 2 files below,

cat file1  "b2f5ff47436671b6e533d8dc3614845d","54fd1711209fb1c0781092374132c66e79e2241b","path/path","output" "8fa14cdd754f91cc6554c9e71929cce7","4a0a19218e082a343a1b17e5333409af9d98f0f5","path/path2","output2" "2510c39011c5be704182423e3a695e91","27d5482eebd075de44389774fce28c69f45c8a75","path/path3","output3"

and other file being,

cat file2 b2f5ff47436671b6e533d8dc3614845d /paths/path 2510c39011c5be704182423e3a695e91 /paths/path2

you can use single awk as

awk 'fnr==nr && nf{gsub(/"/,"",$1); uniquestring[nr]=$1; next}{uniquestring[nr]=$1; next}end{for (i in uniquestring) print uniquestring[i]}' fs="," file1 fs=" " file2

which gives

b2f5ff47436671b6e533d8dc3614845d 8fa14cdd754f91cc6554c9e71929cce7 2510c39011c5be704182423e3a695e91 b2f5ff47436671b6e533d8dc3614845d 2510c39011c5be704182423e3a695e91

the core logic of awk creating array uniquestring index nr; special variable in awk keeps track of line numbers each lines processed in file

the fnr==nr parses first file storing entries in $1 hash-map. since values containing double-quotes, removed using gsub() , field split fs done field ,.

once lines parsed in file1, following {..} part executed on second file file2 again storing entries of $1 in array, field separator set white-space.

after lines processed, end clause used print lines parsed.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
