Rpmbuild copying folders specified by a mapping file

问题

Currently, working with rhel. Need to create a script that can use a mapping file (source and target need to be dynamic). What file type should be used for the mapping file (.csv, .txt, .json)?

• End directory in a slash e.g. src/
• -r can be used against a file e.g. cp -r src/file.fil tgt/
• script will be kicked off by the spec file and files will be copied during build
• source and target need to be dynamic

Script example

cp -r src/file.fil tgt/

Mapping file

<src>\t<tgt>\n e.g. src/file.fil \t tgt/ \n OR 'src/file.fil'\t'tgt/'\n

回答1:

xargs can be used for that

xargs --arg-file your-file.txt cp

file should contain lines like

file1 tgt/
file2 tgt/

or a for loop reading from a file with just source file names provided that your target is constant

for f in $(cat yourfile.txt); do
    cp "$f" tgt/
done

or even

while read src tgt; do
    cp "$src" "$tgt"
done < yourfile.txt
