ターミナル上でファイルの更新日付きのリストを作成する(Linux or 商用UNIX(AIX/HP-UX))

Twitterでそういった処理について見かけたので、備忘として残しておく事にする。
GNU拡張されたlsやfindのあるLinuxであれば処理は結構簡単なのだけど、POSIXのコマンドしか無い場合だとperlとかを使うしか無い。

Linux等の場合なら、lsを使う場合は以下のようにすれば取得が可能だ。

ls -lad $PWD/{.,}* --time-style="+%F %T"|eval awk "'{print" \${6..8}\, "_ }'"
ls -lad $PWD/{.,}* --time-style="+%F %T"|tr -s ' '|cut -d ' ' -f6-
[root@BS-PUB-CENT7-01 ~]# ls -lad $PWD/{.,}* --time-style="+%F %T"|eval awk "'{print" \${6..8}\, "_ }'"

再帰的に取得するのであれば、findのprintfで出力項目を指定できるのでそれを使えばいい。

find ./ -type f -printf '%AF %AT %p\n'
find ./ -type f -printf '%AF %AT %s %p\n' # ついでにファイルサイズも取得する場合
find ./ -type f -printf '%AF %AT %s %p\n' | numfmt --to=iec --field=3 # さらについでにファイルサイズを人間が読みやすいよう加工(numfmtは比較的新し目のOSにしか無いので注意)
[root@BS-PUB-CENT7-01 ~]# find ./ -type f -printf '%AF %AT %p\n'

で、Linuxの場合はこれでいいのだが、商用UNIX(AIXやらHP-UXやら)ではGNU拡張されてるようなコマンドは基本用意されていない。このため、上記のようなコマンドでは出力ができない。
ではどうするかというと、そんなOSでもとりあえずperlは入っているのでそれらで対応するのがいいだろう。以下、実行例(なお、環境はPolarhomeのものを使用している)。

ls -1d $PWD/* | perl -lne 'use POSIX;print POSIX::strftime("%F %T",localtime((stat($_))[9])),"\t",$_'
ls -1d $PWD/* | perl -lne 'use POSIX;print POSIX::strftime("%F %T",localtime((stat($_))[9])),"\t",((stat($_)))[7],"\t",$_' # ファイルサイズも取得する
find $PWD/ -type f | perl -lne 'use POSIX;print POSIX::strftime("%F %T",localtime((stat($_))[9])),"\t",((stat($_)))[7],"\t",$_' # 再帰的に調べる
