/etc/profile에 명시적으로 설정된 환경 변수가 Arch에서 누락되었습니다.

/etc/profile수정하기 전의 모습입니다 .

$ cat /etc/profile
# /etc/profile

# Append "$1" to $PATH when not already in.
# This function API is accessible to scripts in /etc/profile.d
append_path () {
    case ":$PATH:" in
        *:"$1":*)
            ;;
        *)
            PATH="${PATH:+$PATH:}$1"
    esac
}

# Append our default paths
append_path '/usr/local/sbin'
append_path '/usr/local/bin'
append_path '/usr/bin'

# Force PATH to be environment
export PATH

# Load profiles from /etc/profile.d
if test -d /etc/profile.d/; then
    for profile in /etc/profile.d/*.sh; do
        test -r "$profile" && . "$profile"
    done
    unset profile
fi

# Unload our profile API functions
unset -f append_path

# Source global bash config, when interactive but not posix or sh mode
if test "$BASH" &&\
   test "$PS1" &&\
   test -z "$POSIXLY_CORRECT" &&\
   test "${0#-}" != sh &&\
   test -r /etc/bash.bashrc
then
    . /etc/bash.bashrc
fi

# Termcap is outdated, old, and crusty, kill it.
unset TERMCAP

# Man is much better than us at figuring this out
unset MANPATH

이들은 각각 PATH, MANPATH및 다음과 같습니다 INFOPATH.

$ echo $PATH
/usr/local/bin:/usr/bin:/usr/local/sbin:/home/a/.dotnet/tools:/var/lib/flatpak/exports/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl

$ echo $MANPATH

$ echo $INFOPATH

/etc/profileTeX Live를 설치한 후 프로그램이 파일을 찾을 수 있도록 편집했습니다 .

$ cat /etc/profile
# /etc/profile

# Append "$1" to $PATH when not already in.
# This function API is accessible to scripts in /etc/profile.d
append_path () {
    case ":$PATH:" in
        *:"$1":*)
            ;;
        *)
            PATH="${PATH:+$PATH:}$1"
    esac
}

# Append our default paths
append_path '/usr/local/sbin'
append_path '/usr/local/bin'
append_path '/usr/bin'
append_path '/usr/local/texlive/2023/bin/x86_64-linux'

# Force PATH to be environment
export PATH
export MANPATH=/usr/local/texlive/2023/texmf-dist/doc/man:$MANPATH
export INFOMATH=/usr/local/texlive/2023/texmf-dist/doc/info:$INFOPATH

# Load profiles from /etc/profile.d
if test -d /etc/profile.d/; then
    for profile in /etc/profile.d/*.sh; do
        test -r "$profile" && . "$profile"
    done
    unset profile
fi

# Unload our profile API functions
unset -f append_path

# Source global bash config, when interactive but not posix or sh mode
if test "$BASH" &&\
   test "$PS1" &&\
   test -z "$POSIXLY_CORRECT" &&\
   test "${0#-}" != sh &&\
   test -r /etc/bash.bashrc
then
    . /etc/bash.bashrc
fi

# Termcap is outdated, old, and crusty, kill it.
unset TERMCAP

# Man is much better than us at figuring this out
# unset MANPATH

append_path '/usr/local/texlive/2023/bin/x86_64-linux', export MANPATH=/usr/local/texlive/2023/texmf-dist/doc/man:$MANPATH및 을 추가했습니다 export INFOMATH=/usr/local/texlive/2023/texmf-dist/doc/info:$INFOPATH. 나는 또한 그것을 논평했다 unset MANPATH. reboot세 가지 환경 변수는 다음과 같습니다.

$ echo $PATH
/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/local/texlive/2023/bin/x86_64-linux:/home/a/.dotnet/tools:/var/lib/flatpak/exports/bin:/usr/lib/jvm/default/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl

$ echo $MANPATH
/usr/local/texlive/2023/texmf-dist/doc/man:

$ echo $INFOPATH

PATHMANPATH원하는 값으로 변경했지만 여전히 INFOPATH비어 있습니다. 왜 이런 일이 발생합니까?
