すべてをファイルに入れ、並べ替えてから、Awk で処理できます。
# Select all files to move
grep -ircl --exclude=*.{png,jpg,gif,html,jar} '^#\!' /home > list.txt
find /home -type f \( -perm -u+x -o -name "*.sh" \) -print >> list.txt
# Feed them to Awk that will log and move the file
sort list.txt | uniq | awk -v LOGFILE="mylog.txt" '
{ print "Moving " $0 >> LOGFILE
"mv -v --backup \"" $0 "\" /tmp/backup" | getline
print >> LOGFILE }'
編集:いくつかの変数といくつかの追加のチェックを追加することにより、このスケルトンから正式なスクリプトを作成できます。
#!/bin/bash
LIST="$( mktemp || exit 1 )"
LOG="/tmp/mylog.txt"
SOURCE="/home"
TARGET="/tmp/backup"
mkdir -p "${TARGET}"
cd "${SOURCE}" || exit 1
# Select all files to move
grep -ircl --exclude=*.{png,jpg,gif,html,jar} '^#\!' "${SOURCE}" > "${LIST}"
find "${SOURCE}" -type f \( -perm -u+x -o -name "*.sh" \) -print >> "${LIST}"
# Feed them to Awk that will log and move the file
sort "${LIST}" | uniq | awk -v LOGFILE="${LOG}" -v TARGET="${TARGET}" '
{ print "Moving " $0 >> LOGFILE
"mv -v --backup \"" $0 "\" " TARGET | getline
print >> LOGFILE }'
