Bash에서 테이블 열을 정렬하는 방법은 무엇입니까?


표 형식 텍스트를 출력하고 싶습니다. 내가하려고 시도한 것은 배열의 요소를 '\ t'로 에코했지만 잘못 정렬되었습니다. 내 코드

for((i=0;i<array_size;i++));
do
   echo stringarray[$i] $'\t' numberarray[$i] $'\t' anotherfieldarray[$i]
done;

내 출력

a very long string..........     112232432      anotherfield
a smaller string         123124343     anotherfield

원하는 출력

a very long string..........     112232432      anotherfield
a smaller string                 123124343      anotherfield

printf 훌륭하지만 사람들은 그것을 잊어 버립니다.

$ for num in 1 10 100 1000 10000 100000 1000000; do printf "%10s %s\n" $num "foobar"; done
         1 foobar
        10 foobar
       100 foobar
      1000 foobar
     10000 foobar
    100000 foobar
   1000000 foobar

$ for((i=0;i<array_size;i++));
do
    printf "%10s %10d %10s" stringarray[$i] numberarray[$i] anotherfieldarray[%i]
done

%10s문자열에 사용 했습니다. %s중요한 부분입니다. 문자열을 사용하도록 지시합니다. 10중간은 될 것입니다 얼마나 많은 열을 말한다. %d숫자 (숫자)입니다.

man 1 printf 더 많은 정보를 위해서.


열 명령 사용 :

column -t -s' ' filename

필요한 것과 똑같은 출력을 얻으려면 다음과 같이 파일 형식을 지정해야합니다.

a very long string..........\t     112232432\t     anotherfield\n
a smaller string\t      123124343\t     anotherfield\n

그리고 다음을 사용합니다.

$ column -t -s $'\t' FILE
a very long string..........  112232432  anotherfield
a smaller string              123124343  anotherfield

function printTable()
{
    local -r delimiter="${1}"
    local -r data="$(removeEmptyLines "${2}")"

    if [[ "${delimiter}" != '' && "$(isEmptyString "${data}")" = 'false' ]]
    then
        local -r numberOfLines="$(wc -l <<< "${data}")"

        if [[ "${numberOfLines}" -gt '0' ]]
        then
            local table=''

            for ((i = 1; i <= "${numberOfLines}"; i = i + 1))
            do
                local line=''
                line="$(sed "${i}q;d" <<< "${data}")"

                local numberOfColumns='0'
                numberOfColumns="$(awk -F "${delimiter}" '{print NF}' <<< "${line}")"

                # Add Line Delimiter

                if [[ "${i}" -eq '1' ]]
                then
                    table="${table}$(printf '%s#+' "$(repeatString '#+' "${numberOfColumns}")")"
                fi

                # Add Header Or Body

                table="${table}\n"

                local j=1

                for ((j = 1; j <= "${numberOfColumns}"; j = j + 1))
                do
                    table="${table}$(printf '#| %s' "$(cut -d "${delimiter}" -f "${j}" <<< "${line}")")"
                done

                table="${table}#|\n"

                # Add Line Delimiter

                if [[ "${i}" -eq '1' ]] || [[ "${numberOfLines}" -gt '1' && "${i}" -eq "${numberOfLines}" ]]
                then
                    table="${table}$(printf '%s#+' "$(repeatString '#+' "${numberOfColumns}")")"
                fi
            done

            if [[ "$(isEmptyString "${table}")" = 'false' ]]
            then
                echo -e "${table}" | column -s '#' -t | awk '/^\+/{gsub(" ", "-", $0)}1'
            fi
        fi
    fi
}

function removeEmptyLines()
{
    local -r content="${1}"

    echo -e "${content}" | sed '/^\s*$/d'
}

function repeatString()
{
    local -r string="${1}"
    local -r numberToRepeat="${2}"

    if [[ "${string}" != '' && "${numberToRepeat}" =~ ^[1-9][0-9]*$ ]]
    then
        local -r result="$(printf "%${numberToRepeat}s")"
        echo -e "${result// /${string}}"
    fi
}

function isEmptyString()
{
    local -r string="${1}"

    if [[ "$(trimString "${string}")" = '' ]]
    then
        echo 'true' && return 0
    fi

    echo 'false' && return 1
}

function trimString()
{
    local -r string="${1}"

    sed 's,^[[:blank:]]*,,' <<< "${string}" | sed 's,[[:blank:]]*$,,'
}

Not sure where you were running this, but the code you posted would not produce the output you gave, at least not in the bash that I'm familiar with.

Try this instead:

stringarray=('test' 'some thing' 'very long long long string' 'blah')
numberarray=(1 22 7777 8888888888)
anotherfieldarray=('other' 'mixed' 456 'data')
array_size=4

for((i=0;i<array_size;i++))
do
    echo ${stringarray[$i]} $'\x1d' ${numberarray[$i]} $'\x1d' ${anotherfieldarray[$i]}
done | column -t -s$'\x1d'

Note that I'm using the group seperator character (1d) intead of tab, because if you are getting these arrays from a file, they might contain tabs.


It's easier than you wonder.

If you are working with a separated by semicolon file and header too:

$ (head -n1 file.csv && sort file.csv | grep -v <header>) | column -s";" -t

If you are working with array (using tab as separator):

for((i=0;i<array_size;i++));
do

   echo stringarray[$i] $'\t' numberarray[$i] $'\t' anotherfieldarray[$i] >> tmp_file.csv

done;

cat file.csv | column -t

awk solution that deals with stdin

Since column is not POSIX, maybe this is:

mycolumn() (
  file="${1:--}"
  if [ "$file" = - ]; then
    file="$(mktemp)"
    cat >"${file}"
  fi
  awk '
  FNR == 1 { if (NR == FNR) next }
  NR == FNR {
    for (i = 1; i <= NF; i++) {
      l = length($i)
      if (w[i] < l)
        w[i] = l
    }
    next
  }
  {
    for (i = 1; i <= NF; i++)
      printf "%*s", w[i] + (i > 1 ? 1 : 0), $i
    print ""
  }
  ' "$file" "$file"
  if [ "$file" = - ]; then
    rm "$file"
  fi
)

Test:

printf '12 1234 1
12345678 1 123
1234 123456 123456
' > file

Test commands:

mycolumn file
mycolumn <file
mycolumn - <file

Output for all:

      12   1234      1
12345678      1    123
    1234 123456 123456

Just in case someone wants to do that in PHP I posted a gist on Github

https://gist.github.com/redestructa/2a7691e7f3ae69ec5161220c99e2d1b3

simply call:

$output = $tablePrinter->printLinesIntoArray($items, ['title', 'chilProp2']);

you may need to adapt the code if you are using a php version older than 7.2

after that call echo or writeLine depending on your environment.
