Color highlighting in the Bash command line. Bashコマンド用に特定の文字に色を付けるハイライト機能。
It highlights patterns that require attention in logs. ログの表示等で注意すべき文字をハイライトできます。

引数省略したときは、ログを見るときに便利な、主要な注意すべき文字をハイライトします。
cat /var/log/messages | ccolor
tail -f /var/log/syslog | ccolor
This is a command in Bash that simply colors specific words.
引数を省略した場合は、下記ｎのオプションと同じになります。 この内容は随時変更していきます。

This is a command that simply adds color to specific words in Bash. It provides color highlighting.
For example, when viewing large amounts of log files, it is easy to miss important text. This command makes specific words easier to notice by coloring them.
It is written in Bash and awk, and I believe it has a very high level of safety. No network communication occurs.
Although it is highly secure, do not allow third parties to freely input arguments. There is a possibility of some form of injection. This command was created with Claude Code (Ops 4.6).
Bashで特定の単語に色を付けるだけのコマンドです。色ハイライト。
例えば、ログファイルを大量に見る際、重要な文字を見逃すことも多いので、 特定の文字に色をつけて、わかりやすくします。
bashとawkで作られており、安全性が極めて高いと思います。 通信は発生しないので安全です。
安全性は高いとはいえ、引数を第3者に自由に入力できるようにはしないでください。 何らかのインジェクションが発生する可能性があります。
このコマンドはClaude Code (Ops 4.6)で作成しました。
bashスクリプトなので、インストール用のパッケージを作るだけ。
