Decimal and octal are number bases, this only matters when presenting a number (or when inputing a number); the actual number is generally stored in binary in the computer’s memory but this doesn’t often matter to typical programs. In your case, conversion to octal generally involves extracting three bits at a time (since 23 is … Read more
cd /usr/local/scripts/scripts cp -r * ../. //Check to make sure it looks good rm -r /usr/local/scripts/scripts This is super basic…. 2 solved transfer files!!! from a unix server to a linux server [closed]
You can go for the following two solutions: grep -ie ‘b[^e]’ input_file.txt or grep -ie ‘b.’ input_file.txt | grep -vi ‘be’ The first one does use regex: ‘b[^e]’ means b followed by any symbol that is not e -i is to ignore case, with this option lines containing B or b that are not directly … Read more
It can be done pretty easily using Awk, just do the below to store the contents in a bash array. read -p “Enter object to get properties for: ” objectname all_properties=($(awk -F ‘=’ -v input=”${objectname}” ‘$1 ~ input{flag=1; next} $1 ~ /\[object/{flag=0; next} flag && NF {split($0,arr,”=”); print arr[2] } config.ini)) Now loop the array … Read more

Check out your OS Type, 32-bit or 64-bit, by going to ** System Settings -> Details -> Overview,** then select download Linux … Read more
From what we can discern of this question, you’re attempting to create a programmatic rule to rename files ending in extensions stdout-captured, stderr-captured, and status-captured (assuming one typo) into files ending in extensions stdout-expected, stderr-expected, and status-expected, respectively. Obviously, if each of these definitions is inclusive of exactly one file, a rote mv may be … Read more
This looks like the author is comparing Apples to Oranges (no that’s too similar, how about Apples to Aliens). The performance they speak of comes form the result set being displayed in a browser (as a table) instead of waiting for hours for Brio or Toad to return results in a browser (with a crash … Read more
Of course, try this: $0 ~ fun { count = 1 while (! ($0 ~ /{/)) getline getline } count > 0 { if ($0 ~ /{/) count++ if ($0 ~ /}/) count– if ($0 ~ query) print FILENAME “: l” FNR “. ” $0 } And invoke the script like this: awk -v query=”pankaj” … Read more
sed is your friend. The result can be stored in a new file. Give a try to this tested command below: sed s/,/\’,\’/ file.txt > result.txt The sed man page contains information. The test output: $ cat input.txt apple,orange,house foo,bar,woops $ sed s/,/\’,\’/ input.txt > result.txt $ cat result.txt apple’,’orange,house foo’,’bar,woops solved Replacing first occurrence … Read more
The meaning of the word “default” is “implicit”, or “that if none is given”. Here in makefiles, it would be if you call >make without a goal explicitly stated, then the first target in your makefile (other than ones starting with .) is updated. So it makes sense for the first such target to be … Read more
with open(‘path/to/input’) as infile: for line in infile: if line.startswith(“@”): line = line.strip() print(line) print(line.rsplit(“#”, 1)[1]) elif any(line.startswith(e) for e in “#+”): print(line.strip()) solved split a line and print in second line [closed]
The shell first processes input/output redirections like > 5 and attaches the relevant file handles to the file it opens (5 in this case). It also expands * into the matching files in the current directory. So what you end up with is: echo 2 <<ALL YOUR FILES>> is a valid inequality where the output … Read more
This should do the trick: #!/bin/bash INPUT=”$@” SIZE=${#INPUT} for ((i=0; i < ${SIZE}; i++)); do echo “${INPUT}” INPUT=”${INPUT:0:${i}} ${INPUT:$((i+1)):${SIZE}}” #INPUT=”$(echo “$INPUT” | sed “s/^\(.\{${i}\}\)./\1 /”)” done I added a sed option in the comment, although it creates a sub-process when you don’t really have to. 0 solved Linux ‘cut’ command line and replace
