Dotaz: Jak vypnout vypisovani spusteneho prikazu (set +v)

[Rishare2]

Ahoj,

na AIX stroji s ksh mi shell neustale vypisuje na stdout spusteny prikaz. Stejne chovani, jako dela "set -v". Nicmene "set +v" nenahlasi zadnou chybu, ale toto chovani nezmeni. Zajimave take je, ze "set -v" nezpusobi dvojite vypsani tohoto prikazu - vypisuje se stale jednou. Dale je zajimave, ze "normalni" user toto nedela, pouze root (po pouziti "sudo su -")

set +v

Command: set +v
Return Code: 0
Stdout:
set +v
Stderr:

Command: hostname
Return Code: 0
Stdout:
hostname
testaix1

set -v

Command: set -v
Return Code: 0
Stdout:
set -v
Stderr:

Command: hostname
Return Code: 0
Stdout:
hostname
testaix1

Netusi nekdo, jak tento vypis prikazu vypnout? Diky moc.

Hadam, neni to v kshrc?

[Rishare2]

Nevypada to tak. Ale u dlouheho prikazu to zajimave deformuje zadany command.

Command: cat ~/.kshrc;cat ~/.profile;cat /etc/profile;cat /etc/environment
Return Code: 0
Stdout:
cat ~/.kshrc;cat ~/.profile;cat /etc/profile;cat /etc/envi??????????????????????????????????????????????????????????at /etc/profile;cat /etc/envir                            <?????????????????????????????onment

Nebudu nejak kreativne nastavene premenne PS1 PS2 PS3 PS4?

[dushi64]

A co obsahuje /etc/profile.d/secondary_logging.sh ?

[Rishare2]

Omlouvam se za pozdni odpoved.

Takovy soubor na tom serveru neexistuje. Dokonce neexistuje ani /etc/profile.d

[dushi64]

Robi to aj priamy root login cez konzolu (HMC), alebo len sudo su -?

sudo su -

truss -deaf -o /tmp/shell.out ls -d /

cat /tmp/shell.out

[Rishare2]

PS1 az PS4 vypadaji prazdne. I PROMPT_COMMAND tak vypada. Ani po "unset PROMPT_COMMAND" se chovani nezmenilo.

[lertimir]

no možná by pomohlo ten výpis unést. Viz můj malý blog, jak přenést do výstup do jiného terminálu.

[Rishare2]

Dekuji za napad, to bohuzel neni ta spravna cesta k reseni, kterou bychom se v nasem pripade mohli vydat. Delame na reseni, ktere pracuje se statisici servery zaraz a potrebujeme spise standardizovat jejich terminaly. Proto spise hledame cestu, jak toto divne chovani zmenit, nez obejit nejakymi harakiri. Nicmene dekuji za napad.

[pet I.]

A dela to i pri "sudo -i" nebo "sudo ksh"? ksh pripadne s vhodnym parametrem, pro bash se pouziva -l (= login shell)
