shell腳本從csv列讀取並蒐索文件

shell腳本從csv列讀取並蒐索文件

我正在創建一個shell 腳本來從CSV 文件獲取輸入,有兩行(一列提到時間,另一行文件字串)。 ,而且如何我知道它正在搜索哪一行沒有得到文件。

樣本文件:

1300,N213
1245,N218
1400,N222
1600,N225

程式碼,我正在努力讓它發揮作用。

#!/bin/bash
tr_filepath=/var/opt/data/nms_umts_pms_seg/segment1/
echo "Folder to search for traces ${tr_filepath}"
tr_newpath=/var/opt/ericsson/nms_umts_pms_seg/segment1/edos/4G/
CNTRL_FILE=/home/vx622325/filematch.csv
echo "File Contents of ${CNTRL_FILE} to match with pattern"

for i in $CNTRL_FILE;
do

  t=$(cat $i | awk -F"," '{ print $1}')
  n=$(cat $i | awk -F"," '{ print $2}')
  X=`find "$tr_filepath" -type f -iname "A*."$t"*,*="$n"*.bin.gz"`
  echo -e "Traces To Copy \n $X\n" >> /home/vx622325/result_`date +"%d_%m_%Y"`.csv


if [ -d "$tr_newpath" ]; then
        y= cp -rp $X $tr_newpath
else
        echo "Output folder $tr_newpath not found" > /home/vx622325/result_`date +"%d_%m_%Y"`.csv

fi
done

要搜尋的文件

A20190118.2200+0300-2201+0300_SubNetwork=ONRM_RootMo,SubNetwork=N213,MeContext=N213,ManagedElement=1_rnc_gpehfile_Mp0.bin.gz
A20190118.2200+0300-2201+0300_SubNetwork=ONRM_RootMo,SubNetwork=N213,MeContext=N213,ManagedElement=1_rnc_gpehfile_Mp10.bin.gz
A20190118.2200+0300-2201+0300_SubNetwork=ONRM_RootMo,SubNetwork=N213,MeContext=N213,ManagedElement=1_rnc_gpehfile_Mp11.bin.gz

簡化的腳本,假設該文件~vx622325/filematch.csv簡單的CSV 檔案(不嵌入換行符或逗號):

#!/bin/sh

tr_filepath=/var/opt/data/nms_umts_pms_seg/segment1
tr_newpath=/var/opt/ericsson/nms_umts_pms_seg/segment1/edos/4G

result_out=~vx622325/$( date +'result_%d_%m_%Y.log' )

if [ -d "$tr_newpath" ]; then
    printf 'Destination does not exist: %s\n' "$tr_newpath" >"$result_out"
    exit 1
fi

set --
while IFS=, read -r a b; do
   set -- "$@" -o -name "A*.$a*,*=$b*.bin.gz"
done <~vx622325/filematch.csv
shift   # removes the initial "-o"

find "$tr_filepath" -type f \( "$@" \) -exec sh -c '
    dest=$1; shift
    cp "$@" "$dest"/
    printf "Copied: %s\n" "$@"' sh "$tr_newpath" {} + >"$result_out"

read這使用,以逗號作為字段分隔符,從輸入 CSV 檔案中讀取每條記錄到兩個變數a和中b

這些變數用於建立 OR-name模式find

find然後用於查找名稱與模式相符的檔案。檔案被批次複製到目標目錄,其名稱記錄在輸出檔案中。

使用 GNU 工具,您可以執行以下操作:

#!/bin/bash

tr_filepath=/var/opt/data/nms_umts_pms_seg/segment1
tr_newpath=/var/opt/ericsson/nms_umts_pms_seg/segment1/edos/4G

printf -v result_out '%s/result_%(%d_%m_%Y)T.log' ~vx622325 -1

if [ -d "$tr_newpath" ]; then
    printf 'Destination does not exist: %s\n' "$tr_newpath" >"$result_out"
    exit 1
fi

namepats=()
while IFS=, read -r a b; do
   namepats+=( -o -name "A*.$a*,*=$b*.bin.gz" )
done <~vx622325/filematch.csv

find "$tr_filepath" -type f \( "${namepats[@]:1}" \) \
    -exec cp -t "$tr_newpath"/ {} + \
    -printf 'Copied: %p\n' >"$result_out"

正如 msp9011 所提到的,問題在於

for i in $CNTRL_FILE 

其中給出了文件名,您應該給出文件的內容。簡單的方法是準備文件設定內部欄位分隔符號(IFS)如下

while IFS=, read -r column1 column2
do
    echo "column1 : $column1, column2 : $column1"
    #Take action using input
done < $CNTRL_FILE
