我们如何将所有可用的 terminfo 条目（完整的当前编译数据库）与 terminfo 源文件进行比较？
该infocmp实用程序具有该-F选项，但需要比较两个文件，但没有导出所有条目并生成完整当前数据库的文件的选项，需要对每个条目调用它，因此导出每个条目分别条目。如果有一种方法可以一次导出所有条目，则可以分两步完成，调用 infocmp 两次（一次导出所有数据库，另一次比较文件）
答案1
您可以将源代码编译到新目录中并用于infocmp -d比较每个条目。
mkdir -p dir && cd dir
TERMINFO=$PWD tic -x /path/to/terminfo.src
for entry in */*; do
infocmp -x -d -B "$PWD" "${entry#*/}" "${entry#*/}"
done
要仅打印与相关上下文的差异，您可以这样做：
mkdir -p dir && cd dir
TERMINFO=$PWD tic -x /path/to/terminfo.src
for entry in */*; do
LC_ALL=C infocmp -x -d -B "$PWD" "${entry#*/}" "${entry#*/}" |
awk '
/^comparing/ {entry=$1" "$2; next}
$1 == "comparing" {section=$0; next}
entry {print entry; entry = 0}
section {print section; section = 0}
{print}'
done
答案2
我用这个脚本来做到这一点（例如在 Debian 上，它假设kbs是^?），测试 ncurses 的本地构建：
#!/bin/sh
# $Id: test-terminfo+,v 1.10 2012/04/21 15:52:17 tom Exp $
# vi:sw=4 ts=4
# Compile the given terminfo source-file(s) into a temporary directory, compare
# the compiled files against the system version.
if test $# = 0 ; then
with-local-ncurses $0 terminfo terminfo.src
else
OPTS=-x
MY_NCURSES=/usr/local/ncurses
MY_TERMINFO=$MY_NCURSES/share/terminfo
PATH=$MY_NCURSES/bin:$PATH; export PATH
unset TERMINFO_DIRS
unset TERMINFO
TMP=/tmp/term$$
rm -rf $TMP
trap "rm -rf $TMP" 0 1 2 3 15
mkdir $TMP
rm -f $TMP/terminfo.sed
cat >$TMP/terminfo.sed <<EOF
s,/usr/share,$MY_NCURSES/share,g
/^xterm+kbs|fragment for backspace key, kbs=/s/kbs=^H,/kbs=^?,/
/^xterm+kbs|fragment for backspace key,\$/,/^#/{
s/kbs=^H,/kbs=^?,/
}
EOF
for name in $*
do
if test -f "$name" ; then
sed -f $TMP/terminfo.sed $name >$TMP/source
TERMINFO=$TMP tic -U $OPTS -R ALL $TMP/source
fi
done
TERMINFO=$MY_TERMINFO
for name in $TMP/?/*
do
base=`dirname $name`
base=`basename $base`
name=`basename $name`
case $name in
??) # ignore 2-char termcap names
;;
*)
if test -f "$TERMINFO/$base/$name" ; then
infocmp -U $OPTS -q -p -f -A $TERMINFO -B $TMP $name $name
else
echo missing "$name $base"
fi
;;
esac
done
fi

我检查差异（除了丢失的条目）通过查找tab字符。
至于为什么命名为test-terminfo+，这是因为原始脚本（写于 1998 年）仅与系统 terminfo 进行比较（没有任何软件包可以避免污染...）。
像往常一样，阅读手册页会有所帮助：
