我想突出显示年历中的多个日期。在UNIX下可以吗？

您可以编写一个脚本来调整cal输出，例如使用任何 awk：
$ cat tgtDates
January 25
June 13
$ cat tst.sh
#!/usr/bin/env bash
cal 2022 |
awk '
BEGIN {
highlightOn = "["
highlightOff = "]"
}
NR==FNR {
tgtDates[$0]
next
}
NF == 3 { split($0,months); print; next } # month list
!/[0-9]/ { print; next } # blank line or days list
{ # dates list
for ( mthNr=1; mthNr<=3; mthNr++ ) {
mthName = months[mthNr]
inDayNrs = substr($0,1,20)
outDayNrs = ""
while ( match(inDayNrs,/[0-9]+/) ) {
inDayNr = substr(inDayNrs,RSTART,RLENGTH)
curDate = mthName " " inDayNr
outDayNr = (curDate in tgtDates ? highlightOn inDayNr highlightOff : inDayNr )
outDayNrs = outDayNrs substr(inDayNrs,1,RSTART-1) outDayNr
inDayNrs = substr(inDayNrs,RSTART+RLENGTH)
}
printf "%s ", outDayNrs inDayNrs
$0 = substr($0,24)
}
print ""
}

显然，我只是将目标日期包装在[...]上面，以便它们可见以显示命令正在工作，这就是导致行布局移动、为日期着色而不是仅更改的原因：
highlightOn = "["
highlightOff = "]"
更改背景和/或前景色以突出显示的内容，您甚至可以为您喜欢的任何不同类型的事件设置不同的背景/前景色，例如：
$ cat tgtDates
January 25 Birthday
June 13 Meeting
September 2
December 25 Holiday
$ cat tst.sh
#!/usr/bin/env bash
cal 2022 |
awk -v today="$(date +'%B %-d')" '
BEGIN {
split("BLACK RED GREEN YELLOW BLUE MAGENTA CYAN WHITE",tputColors)
for (i in tputColors) {
colorName = tputColors[i]
colorNr = i-1
cmd = "tput setaf " colorNr
fgEscSeq[colorName] = ( (cmd | getline escSeq) > 0 ? escSeq : "<" colorName ">" )
close(cmd)
cmd = "tput setab " colorNr
bgEscSeq[colorName] = ( (cmd | getline escSeq) > 0 ? escSeq : "<" colorName ">" )
close(cmd)
}
cmd = "tput sgr0"
colorOff = ( (cmd | getline escSeq) > 0 ? escSeq : "<sgr0>" )
close(cmd)
highlight["Today"] = bgEscSeq["BLACK"] fgEscSeq["WHITE"]
highlight["Holiday"] = bgEscSeq["RED"] fgEscSeq["YELLOW"]
highlight["Birthday"] = bgEscSeq["CYAN"] fgEscSeq["RED"]
highlight["Meeting"] = bgEscSeq["YELLOW"] fgEscSeq["GREEN"]
highlight[""] = bgEscSeq["GREEN"] fgEscSeq["WHITE"]
tgtDates[today] = "Today"
}
NR==FNR {
tgtDates[$1" "$2] = $3
next
}
NF == 3 { split($0,months); print; next } # month list

感谢这个 awk 脚本。这很棒，但我必须做一些小的调整才能使其在 Ubuntu 中运行。我已经在 Ubuntu 20.04.4 LTS 和 18.04.6 LTS 中成功测试了它。
所做的更改是：（采用新旧格式的差异）
2c2
< cal 2022 |
---
> ncal -bh 2022 |
55,56c55,56
< printf "%s ", outDayNrs inDayNrs
< $0 = substr($0,24)
---
> printf "%s ", outDayNrs inDayNrs
> $0 = substr($0,23)
为简单起见，修订如下：
#!/usr/bin/env bash
ncal -bh 2022 |
awk -v today="$(date +'%B %-d')" '

split("BLACK RED GREEN YELLOW BLUE MAGENTA CYAN WHITE",tputColors)

close(cmd)
cmd = "tput setab " colorNr
bgEscSeq[colorName] = ( (cmd | getline escSeq) > 0 ? escSeq : "<" colorName ">" )
close(cmd)
}
cmd = "tput sgr0"
colorOff = ( (cmd | getline escSeq) > 0 ? escSeq : "<sgr0>" )
close(cmd)
