我有一個頂級目錄路徑,我想將所有相對路徑轉換爲該目錄內所有文件中存在的絕對路徑。 例如我有這樣的目錄結構:將相對路徑轉換爲絕對路徑的Bash&Perl腳本

內容 top_level.ext1
$ tree 
. 
|-- DIR 
| |-- inner_level.ext1 
| `-- inner_level.ext2 
|-- top_level.ext1 
`-- top_level.ext2 

../../a/b/c/filename_1.txt 
../../a/d/e/filename_2.txt 

假設頂級目錄路徑是/this/is/the/abs/dir/path/

想要的top_level.ext1內容轉換爲:

/this/is/the/abs/a/b/c/filename_1.txt 
/this/is/the/abs/a/d/e/filename_2.txt 

內容top_level.ext2

cc_include+=-I../../util1/src/module1/moduleController -I../../util/src/module1/module2Controller; 
cc_include+=-I../../util2/src/module2/moduleUtility; 

想要的top_level.ext2到的內容轉換:

cc_include+=-I/this/is/the/abs/util1/src/module1/moduleController -I/this/is/the/abs/util/src/module1/module2Controller; 
cc_include+=-I/this/is/the/abs/util2/src/module2/moduleUtility; 

另外,想通過內部DIR文件應用此相同的轉換。

例如 內容DIR/inner_level.ext1

../../../a/b/c/filename_1.txt 
../../../a/d/e/filename_2.txt 

希望將內容轉換的DIR/inner_level.ext1到:

/this/is/the/abs/a/b/c/filename_1.txt 
/this/is/the/abs/a/d/e/filename_2.txt 

同爲DIR/inner_level.ext2也。

已經寫了這兩個腳本。

top_level.ext1的轉換成功。

file_manager.sh

#!/usr/bin/bash 
file='resolve_path.pl' 
basedir='/this/is/the/abs/dir/path' 

run_perl(){ 
    echo -e "\n File getting modified: $1" 
    cp $1 tmp.in 
    perl $file 
    mv tmp.out $1 
    rm tmp.in 
} 

find $basedir -type f |while read inputfile 
do 
    run_perl $inputfile 
done 

resolve_path.pl

#!/usr/bin/perl 
use strict; 
use warnings; 
use Data::Dumper; 
use 5.010; 
use Switch; 

#****************************************************** 
#  Set-up Directory And Input/Output File Names

our $in_file = glob('tmp.in'); 
my $out_file1 = 'tmp.out'; 
print "Input file: $in_file\n"; 

#************************************ 
#  Local and Global Variables 
#************************************* 
my $current_path = "/this/is/the/abs/dir/path"; 
my $temp_path = $current_path; 

#************************************

#************************************ 
open(READ, $in_file) || die "cannot open $in_file"; 
open(WRITE, ">$out_file1") || die "cannot open $out_file1"; 


#****************************************************** 
#  Read The Input [*.out] File Line By Line 
#****************************************************** 
while (<READ>) { 
    if(/^(\.\.\/){1,}(\w+\/)*(\w+).(\w+)/){ 
     my $file_name = $3; 
     my $file_ext = $4; 

     my @count = ($_ =~ /\.\.\//g); 
     my $cnt = @count; 

     my @prev_dir = ($_ =~ /\w+\//g); 
     my $prev_dir_cnt = @prev_dir; 
     my $file_prev_dir = join('', @prev_dir); 

     $temp_path = $current_path; 
     for(my $i=0; $i<$cnt; $i++){ 
      if($temp_path =~m/(\/.*)\/\w+/){ 
       $temp_path = $1; 
      } 
     } 

     print WRITE "$temp_path"."\/"."$file_prev_dir"."$file_name"."\."."$file_ext"."\n"; 

    } else { 
     print WRITE "$_"; 
    } 
} 

我面臨的問題:

  1. 沒有轉換被應用在top_level.ext2 & DIR/inner_level.ext2 因爲我的Perl腳本不能正確解析爲../(即 cc_include+=-I即將開始)。從絕對路徑相對路徑

  2. 轉換工作不正常 爲DIR/inner_level.ext1和錯誤的路徑越來越 追加。

如果有人可以在我的腳本中提出預期的更改以解決上述兩個問題,那將會很有幫助。
