Locateコマンドの出力は少しおとなしいです:
$ time locate etc/profile
/etc/profile
/etc/profile.d
/etc/profile.d/appmenu-qt5.sh
/etc/profile.d/apps-bin-path.sh
/etc/profile.d/bash_completion.sh
/etc/profile.d/cedilla-portuguese.sh
/etc/profile.d/jdk.csh
/etc/profile.d/jdk.sh
/etc/profile.d/vte-2.91.sh
real 0m0.696s
user 0m0.671s
sys 0m0.024s
ll
やls -la
のように、どうすれば詳細情報を提供できますか?おそらく見出しも含めますか?
この目的でllocate
というスクリプトを作成しました。
$ time llocate etc/profile

通常のlocate
コマンドの.76
秒に対して、実行には.70
秒かかります。違いはごくわずかです。
Bashコードはかなり単純です。以下のスクリプトをディレクトリ/home/YOUR_NAME/bin
(最初に作成する必要がある場合があります)または/usr/local/bin
にコピーし、次を使用して実行可能としてマークします。
chmod a+x /home/YOUR_NAME/bin/llocate`
これがスクリプトllocate
です。
#!/bin/bash
# NAME: llocate
# PATH: /mnt/e/bin
# DATE: May 22, 2018. Modified July 1, 2018.
# DESC: Use locate command but format output like `ll` with headings
# PARM: Parameter 1 = locate search string
# UPDT: 2018-07-01 Format date with Time or Previous Year like `ls -al`.
if [[ $# -eq 0 ]]; then
echo "First parameter must be full or partial file names to search for."
exit 1
fi
# Create unqique temporary file names
tmpLine=$(mktemp /tmp/llocate.XXXXX)
tmpForm=$(mktemp /tmp/llocate.XXXXX)
# Function Cleanup () Removes temporary files
CleanUp () {

[[ -f $tmpForm ]] && rm -f $tmpForm # at various program stages.
}
locate "$1" > $tmpLine
# Was anything found?
if [[ ! -s $tmpLine ]] ; then
echo "No files found. If files created today, did you run 'Sudo updatedb' after?"
CleanUp
exit 1
fi
LastRun=$(stat --printf=%y /var/lib/mlocate/mlocate.db | sed 's/\.[^\n]*//')

# Format date with time if it's this year, else use file's year
if [[ $(date -d @$Seconds +'%Y') == $(date +%Y) ]]; then

else
HumanDate=$(date -d @$Seconds +'%b %_d %Y')
fi
StatLine="${StatLine/$Seconds/$HumanDate}"
echo "$StatLine" >> $tmpForm
done < $tmpLine # Read next locate line.
cat $tmpForm | column -t -s '|'
CleanUp
exit 0
xargs
およびls
の使用:
$ locate -0 etc/profile | xargs -0 ls -ld
