Re: [solved] man terminates with error when tries to open some man pages

Do you have "man" aliased somewhere? Are you using oh-my-zsh, or anything like it?

Re: [solved] man terminates with error when tries to open some man pages

Oh, I found the problem. The problem was, I reexported PAGER and LESS variables in one function in .bashrc. Actually, psql command was redefined as function in ~/.bashrc.

psql() {
    YELLOW=$(printf "\e[1;33m" )
    LIGHT_CYAN=$(printf "\e[1;36m" )
    NOCOLOR=$(printf "\e[0m"    )
    RED=$(printf "\e[1;31m" )

    PAGER="sed \"s/\([[:space:]]\+[0-9.\-]\+\)$/${LIGHT_CYAN}\1$NOCOLOR/;"
    PAGER+="s/\([[:space:]]\+[0-9.\-]\+[[:space:]]\)/${LIGHT_CYAN}\1$NOCOLOR/g;"
    PAGER+="s/|/$YELLOW|$NOCOLOR/g;s/^\([-+]\+\)/$YELLOW\1$NOCOLOR/\" 2>/dev/null  | less"

    env psql "$@"
}

I have changed it to:

psql() {
    YELLOW=$(printf "\e[1;33m" )
    LIGHT_CYAN=$(printf "\e[1;36m" )
    NOCOLOR=$(printf "\e[0m"    )
    RED=$(printf "\e[1;31m" )

    #export LESS="-iMSx4 -FXR"

    PAGER="sed \"s/\([[:space:]]\+[0-9.\-]\+\)$/${LIGHT_CYAN}\1$NOCOLOR/;"
    PAGER+="s/\([[:space:]]\+[0-9.\-]\+[[:space:]]\)/${LIGHT_CYAN}\1$NOCOLOR/g;"
    PAGER+="s/|/$YELLOW|$NOCOLOR/g;s/^\([-+]\+\)/$YELLOW\1$NOCOLOR/\" 2>/dev/null  | less"
    #export PAGER

    PAGER=$PAGER LESS=$LESS env psql "$@"
}

Re: [solved] man terminates with error when tries to open some man pages

You could also use

psql() (
    ...
)

(note the parentheses instead of the curly braces)

This will run the code inside the function in a sub shell, so variable declarations and exports should not affect your running shell.

Re: [solved] man terminates with error when tries to open some man pages

Or you could just use local variables, so they don't leak outside the function...
