The file itself 32# is not deleted, as under VC with vc-keep-workfiles at its default of t, but 33# all the version files are. 34# 35# If an argument file is already version-controlled under RCS, any version 36# files are added to the list of deltas and deleted, and then the workfile 37# is checked in again as the latest version. This is probably not quite 38# what was wanted, and is the main reason VC doesn't simply call this to 39# do checkins. 40# 41# This script is intended to be used to convert files with an old-Emacs-style 42# version history for use with VC (the Emacs 19 version-control interface), 43# which likes to use RCS as its back end. It was written by Paul Eggert 44# and revised/documented for use with VC by Eric S. Raymond, Mar 19 1993. 45 46case $# in 470) 48 echo "rcs-checkin: usage: rcs-checkin file ..." 49 echo "rcs-checkin: function: checks file.~*~ and file into a new RCS file" 50 echo "rcs-checkin: function: uses the file's first line for the description" 51esac 52 53# expr pattern to extract owner from ls -l output 54ls_owner_pattern='[^ ][^ ]* *[^ ][^ ]* *\([^ ][^ ]*\)' 55 56for file 57do 58 # Make it easier to say `rcs-checkin *' 59 # by ignoring file names that already contain `~', or end in `,v'. 60 case $file in 61 *~* | *,v) continue 62 esac 63 # Ignore non-files too. 64 test -f "$file" || continue 65 66 # Check that file is readable. 67 test -r "$file" || exit 68 69 # If the RCS file does not already exist, 70 # initialize it with a description from $file's first line. 71 rlog -R "$file" >/dev/null 2>&1 || 72 rcs -i -q -t-"`sed 1q $file`" "$file" || exit 73 74 # Get list of old files. 75 oldfiles=` 76 ls $file.~[0-9]*~ 2>/dev/null | 77 sort -t~ -n -k 2 78 ` 79 80 # Check that they are properly sorted by date. 81 case $oldfiles in 82 ?*) 83 oldfiles_by_date=`ls -rt $file $oldfiles` 84 test " $oldfiles 85$file" = " $oldfiles_by_date" || { 86 echo >&2 "rcs-checkin: skipping $file, because its mod times are out of order. 87 88Sorted by mod time: 89$oldfiles_by_date 90 91Sorted by name: 92$oldfiles 93$file" 94 continue 95 } 96 esac 97 98 echo >&2 rcs-checkin: checking in: $oldfiles $file 99 100 # Save $file as $file.~-~ temporarily. 101 mv "$file" "$file.~-~" || exit 102 103 # Rename each old file to $file, and check it in. 104 for oldfile in $oldfiles 105 do 106 mv "$oldfile" "$file" || exit 107 ls_l=`ls -l "$file"` || exit 108 owner=-w`expr " $ls_l" : " $ls_owner_pattern"` || owner= 109 echo "Formerly ${oldfile}" | ci -d -l -q $owner "$file" || exit 110 done 111 112 # Bring $file back from $file.~-~, and check it in. 113 mv "$file.~-~" "$file" || exit 114 ls_l=`ls -l "$file"` || exit 115 owner=-w`expr " $ls_l" : " $ls_owner_pattern"` || owner= 116 ci -d -q -u $owner -m"entered into RCS" "$file" || exit 117done 118 119# arch-tag: 89c86949-ef04-4380-838b-bc1444dcb074 120
