awkスクリプトの作業ディレクトリを変更したい:
...
path="./some/path"
system("pwd") ; \
current_dir=system("pwd") ; \
pushd_cmd="pushd " path ; \ # a "cd" doesn't work too
print pushd_cmd ; \
system(pushd_cmd) ; \
system("pwd"); \ # the same directory as before
type="xml"
ls_cmd = "ls *." type; # so I can't find the files. Specifying with "./some/path/*.xml" doesn't work too (without trying to change the working directory)
...
私の場合、なぜシステムが効果がないのか誰かが知っていますか?
