lowriter Bash 将所有文档就地转换为 pdf 的脚本

Question

So.. I've been tasked with converting a bunch of *.doc files to *.pdf utilizing lowriter

What I would like to do is do this in place, but since there is no option to do that using lowriter , I figured I would capture the originating file and path, capture the conversion, and then move the converted file to the originating path, and then delete the original *.doc

The problem is my sed and or awk is weak at best;) so I cannot figure out how I can "capture" the converted file name from the output.

My Code:

#!/bin/bash

FILES=/my/path/**/*.doc

shopt -s globstar

for f in $FILES; do

    the_file=$f;
    the_orig_dir=$(dirname "$the_file") ;

    converted=$(lowriter --headless --convert-to pdf "$the_file");
    
    echo $converted;
done;

and the output is:

convert /my/path/Archives/Ally/Heavenly Shop.doc -> /my/Heavenly Shop.pdf using filter : writer_pdf_Export
convert /my/path/Archives/Ally2/Solutions Shop.doc -> /my/Solutions Shop.pdf using filter : writer_pdf_Export
convert /my/path/Archives/Ally3/Xpress Shop.doc -> /my/Xpress Shop.pdf using filter : writer_pdf_Export

What I need to do is capture the path/filename of the converted file after the -> and before the : . I just don't know how I can do this. Can someone tell me?

The quick answer to the question you asked is that this will work using any sed:

sed 's/.*-> \(.*\) using filter :.*/\1/'

but I'm not sure you actually need to do that. Based on what you posted and your comments under the question I think all you really need is:

#!/usr/bin/env bash

shopt -s globstar

docPaths=( /my/path/**/*.doc )

for docPath in "${docPaths[@]}"; do

    pdfPath=$(basename "$docPath" '.doc')'.pdf'

    lowriter --headless --convert-to pdf "$docPath"
    
    printf '%s\n' "$pdfPath"

done

Answer 2

#!/bin/bash

FILES=/my/specific/input/folder/**/*.doc

shopt -s globstar

for f in $FILES; do

    the_file=$f;
    the_orig_dir=$(dirname "$the_file") ;

    converted=$(lowriter --headless --convert-to pdf "$the_file");
    
    new_file=$(echo "$converted" | grep -o -P '(?<= -> ).*(?= using filter : )');
    
    new_file_name=$(basename "$new_file");
    
    
    echo "$the_orig_dir/$new_file_name";
    
    
    set -x;
    
    rm -f $the_file;
    
    mv "$new_file" "$the_orig_dir/";
    
    set +x;
    
done;

does what I need it to do

Following on comment from ed motron, worth mentioning that the libraOffice writer will place the output file in predictable name, based on the --outdir (or current working folder), and the requested conversion (pdf). The rules can be used to construct the name of the output file.

The above script can simply be written:

FILES=/my/path/**/*.doc

shopt -s globstar

for f in $FILES; do

    lowriter --headless --convert-to pdf "$f"
    converted=$(basename "$f" .doc).pdf
    # Do something with converted ...    
    echo "Output: $converted"
done;
