linux - Terminal only shows $ -

-

i tried building own linux distribution , follow linux scratch book. when tried entering following commands in bashrc.

set +h  umask 022  lfs=/mnt/lfs  lc_all=posix  path=/tools/bin:/bin:/usr/bin  export lfs lc_all path

after when restart terminal. seeing $ symbol. thought entry made in bashrc problem. so, reverted , restarted system too. but, still seeing same problem. also, auto completion not working. please, me rid of this.

welcome stackoverflow
should set 'ps1' variable. search it
ps1, example:

\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\[\033[00;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
